Hi, I’m Dark, here to explain not-cat genetics in a way that is simpler (for me).
If you prefer detailed explanations there is the official tutorial.

I also have a breeding guide

Not-Cat Genetics
Not-Cats genome strings are displayed as such:
[C] [NN] [SS] [BBFF4] [NNMS] [NN0C] [AA] [BB]

They separate out into these categories:
[C] - Species
[NN] - Wind
[SS] - Fur Type
[BBFF2] - Color
[NNMS] - Pattern
[NN0C] - White Marks
[AA] - Growth Pattern
[BB] - Mystery Gene

Under each category is a variety of alleles that can be realised in a not-cat.

Species:
C - Not-Cat
There are plans for more species to be made, I will update as needed.

Wind:
N - North
S - South
O - Null (recessive)

Fur Type:

Y - ?
At the moment this gene has no effect on not-cats. Squid has said they were added for future species. I have nicknamed this gene the Blurry Gene [BLRY] because of the alleles and the fact that we can’t see what it’s for yet.

Now that we know what all the alleles are, let’s see what happens when they come together in a not-cat. For any of the recessive alleles, there must be two for the recessive gene to realise.

Realisations of Genome Strings

Species:
There is currently only one, being a not-cat [C]


Wind:
[NN] & [NO] & [ON] = North Wind
[SS] & [SO] & [OS]= South Wind
[NS] & [SN] = Trade Wind
[OO] = Null Wind (recessive)


Fur:
[SS] & [SL] & [LS] = Shorthair
[LL] = Longhair (recessive)



Colour:
This requires a table


North or South not-cats have their colour realised through the First allele for North cats, and the Second allele for South cats [North > O|B < South]. To save space here I will just use a single colour allele, which can be placed in either First or Second space for North or South not-cats.



Trade Not-Cats:
Trade not-cats have special rules for their colours, and their colour allele placement matters. When both alleles match, you get a watercolour in that colour. When the alleles differ you get a tortoiseshell in the colour of the First allele. In the Appearance section of a not’s cats page, the colour will display as two colours. Watercolours use the genetic density, and the colour of one density below that. Trades use a matching B-O / O-B pairing, where the dilution and density match for both.
NOTE: When Watercolours are density 1, their second colour will be Snow
Watercolours:


Tortoiseshells:




Pattern:

(Mackerel, Classic, Broken, Lynxpoint. Clouded, Rosette, Cloudpoint. Spotted, Mink, Colourpoint, Solid.)
Pattern Realised or not:
[YY] & [YN] & [NY] = Patterned cat
[NN] = Solid cat (ignore pattern info)

Realised Pattern
[TT] = Mackerel Pattern
[TM] & [MT]= Classic Pattern
[TS] & [ST]= Broken Pattern
[TP] & [PT]= Lynxpoint Pattern
-
[MM] = Clouded Pattern
[MS] & [SM]= Rosette Pattern
[MP] & [PM]= Cloudpoint Pattern
-
[SS] = Spotted Pattern
[SP] & [PS]= Mink Pattern
-
[PP] = Colorpoint Pattern


White Marks:

White or No White:
[Y] & [YN] & [NY] = White Marks
[NN] = No White Marks

How much White:




Growth
Growth is used for predicting the total stats a kitten will have as an adult. By knowing the growth genotype, you can calculate their full stats.
[AA] = Very Early
[AB] = Early
[AC] = Decreasing

[BA] = Arch
[BB] = Steady
[BC] = Dip

[CA] = Very Late
[CB] = Late
[CC] = Increasing

Now, yes, the C set is scaled backwards in terms of the pattern in the other two sets, however this was intentionally coded.
You can also find the following quote and graph here.



I have also made a colour coded table because I like colours and tables.

You can clearly see the colour gradient in the Kittens column, going from green, to yellow, to pale orange, to bold orange, to red. It is ordered green to red as fastest growth to slowest growth.


Blurry Gene
We have no information yet as to what this gene will do, and so there are no realisations.

How to Genome your Not-Cats

Time for some fun; writing out your Not-Cats Genome string.

If you want the guide with images please click here

The Easy Part
You can get the bulk of the genome string from the Appearance Information of your not-cats.
This is Darkfang, a North wind not-cat

This is her Appearance Information

From this we can already tell that she is a Not-Cat [C], she is Northwind [N?], is a Longhair [LL], Black fur [B?F?4], Mackerel Pattern [Y?TT], and has White Bib, Boots, & Belly [Y?5C], (where ? means an allele we don’t know.)
Species- C
Wind - N?
Fur Type - LL
Colour - B?F?4
Pattern - Y?TT
White Marks - Y?5C

The Question Marks [N? etc] mean that we aren’t 100% sure which allele she has, whether two dominants, or a dominant and recessive. This is where genome testing comes in.

The Less Easy Part
For now, I’m going to explain this without images, but if people would like some I can put them on a to-do list.
To test unknown alleles we can use the Beans Sandbox, in which you combine two Not-cats to see potential beans.
The basic rule for testing recessive or invisible alleles, is to use a not-cat that you have a confirmed genome string for. You also want to preview at least five different bean sets to be sure that there is no recessive/invisible allele.



MAJOR DISCLAIMER: There is a very rare “mutation” called the “Pushy North Gene.” Squid has explained it here. In essence, there is an unknown probability (all we know is “very rare”) that a North/South pairing can produce beans with duplicate replica genes of the North parent. (There are rumours that beans born in the South, when we get more locations, could have duplicate replicas pushed by the South parent, but we aren’t there yet). This has a theoretical chance of occurring with all paired allele genes. The effect in sandbox testing is that you may have a pushed bean show up. So far this has been witnessed with Null cats appearing when only one parent has a null allele. I recommended refreshing to see if more appear, because a standard null recessive pairing has a much higher chance of nulls and you will see more quite quickly. Ultimately, just make sure you roll multiple instances before confirming a gene.

Users Tanya, nap, ghost, mayanaz, and tammoratya have been kind enough to allow the use of their not-cats in testing.
DISCLAIMER - Do not go from this guide to contact the owners to breed from or buy these not-cats!

Null Testing
To test for the Null allele in a North or South not-cat (Trade not-cats cannot have a null allele), you use a South or North not-cat with a confirmed null allele.
For North not-cats, use South 747 [SO]
For South not-cats, use North 2509 [NO]
If any of the beans result in a null not-cat, easily spotted with snow colour, then your not-cat has a null allele.
Darkfang produced no null beans, so her Wind gene is [NN]

Recessive Longhair Testing
To test for a Longhair allele you can use any Longhair not-cat, or Tradewind 983 [LL]
If any of the beans result in a Longhair not-cat, then your not-cat has a Longhair allele.
Darkfang is a Longhair, so her Fur gene is [LL]

Orange and Black Testing
To test a North or South not-cat’s invisible colour allele, you need to use a [BB] or [OO] not-cat.
To test for invisible orange in a black not-cat, use Tradewind 983 [BB].
To test for invisible black in an orange not-cat, use Tradewind 3038 [OO]
If your black not-cat produces any orange beans, or your orange not-cat produces any black beans, then your not-cat has an invisible allele of the opposite colour (e.g. [OB] or [BO])
Albino Note: Albinos display no Colour genes so you will have to test both colours. For albinos with both a B and an O there is no way to tell the order, so I generally just go alphabetical with [BO]
Darkfang only produced Black beans, so her Colour Group gene is [BB]

Recessive Dilute Testing
To test for a Dilute allele, use any Dilute not-cat (greys or creams), or Tradewind 983 [DD]
If any of the beans result in a dilute not-cat, then your not-cat has the Dilute allele. For this test you really have to know what the colours look like so feel free to also use the cat sandbox to double check colouring.
Albino Note: No displayed Colour genes means no displayed Colour Strength. In testing, if your albino makes only Full colour beans they are [FF]; Full and Dilute means [FD]; only Dilute means [DD].
Darkfang only produced Full beans, so her Secondary Colour gene is [FF]

Colour Density in Albinos
Because Albinos don’t display Colour genes, we also need to test for their colour density [1-4]. To test for Colour Density, use any cat you know the Density of, or 983 [BBDD4]. You will have to be able to recognise the colours, or have the cat sandbox handy to double check. The black and grey groupings are easier to distinguish colours than the orange and cream groupings, so I recommend focusing on those (which 983 will make in the box).
Identify how many different colours from one group are produced as beans. 983 will always produce black[F?4] or charcoal[DD4] beans (depending on the Colour Strength, Full or Dilute, of the cat being testing), so we just need to see whether the beans also get Chocolate[3] or Grey[3], Brown[2] or Smoke[2], or Tan[1] or Silver[1]. The palest Density bean produced is the Density of your cat.
Darkfang is not an Albino, but in testing she only produces Density [4] with 983.

Recessive Solid Testing
Solid is a cat with no patterning [NN]. To test for a Solid allele, use any Solid not-cat, or Tradewind 983 [NN].
If any of the beans result in a solid not-cat, then your not cat has the Solid allele.
Albino Note: Albinos also show no pattern. In testing, if your albino makes only Patterned beans they are [YY]; Patterned and Solid means [YN]; only Solid means [NN]
Darkfang only produced Patterned beans, so her Initial Pattern gene is [YY]

Pattern Testing in Solids (and Albinos)
If your not-cat is solid (or Albino), they still have a Main Pattern gene, it’s just hidden. To test for their hidden Pattern, use any not-cat with a double gene (Mackerel [TT], Clouded [MM], Spotted [SS], Colourpoint [PP]), or Tradewind 2534 [TT].
Look at the patterns on the resulting beans (you may need to double check in sandbox to recreate them). Using 2534, if they only produce [TT] then your not-cat is [TT]. If they only produce [TT] and [TS] then your not-cat is [TS]. If they only produce [TS], your not cat is [SS]. Producing [TM] and [TP] makes your not-cat [MP], etc etc. I’m working on a breeding guide that will go into patterns further.

Recessive No White Testing
To test for a No White allele on a cat with White Spots, use any white spotted not-cat with confirmed [YN], or Tradewind 983 [YN1].
Note: You can use an NN cat as long as they are confirmed to be 1 or higher. NN0 will give false results.
If any of the beans result in a not-cat with No White, then your not-cat has a No White allele.
Note: Do not count any bean poses that hide Locket (sleeping, playing). Preview closer to ten times to test more beans that show all white mark options.
Darkfang did not produce any No White beans, so her Initial White gene is [YY]

N|N vs 0 Testing
To test whether a No White not-cat is [NN] or [Y(Y/N)0], use any cat with [NN] and a number of 1 or higher, or Tradewind 36925 [NN10]
If any of the beans show any white, then your not-cat is a [Y(Y/N)0]. If they show no white then your not-cat is [NN?].
Note: The only way to see if your not-cat is [YY0] vs [YN0] is to look at the percentage of beans that have white in this test. If it is around 50/50, your cat is most likely [YN]. If it is greater than this, your cat is most likely [YY].
Note: This used to use [NN4] 1380, however with [NN10] there is a greater chance of more white shown (when shown) and less chance to miss small amounts of white
Note: If your No White not-cat is custom or gifted from Nestor then they are [NN0]. This is going to be adjusted in future, but for now this is how you figure it out for those not-cats. This was adjusted on May 21, 2022, 14:50. Any migrated not-cats with ID’s higher than 11358 have the possibility of [NN] with a number greater than 0.

N|N White Number Testing
Note: This is for born/fostered not-cats, and any custom or migrated not-cats with ID’s higher than, 11358. Custom/migrated not-cats below this ID are still [NN0].
To test the White number of your N|N not-cat, use any cat with [Y(Y/N)0], or Tradewind 15075 [YY0].
If any of the beans show white then you have a numbered [NN]. Preview the beans to find the highest white number that is produced and that is your not-cat’s number.
Note: This used to use [YN0] 2361, however with a [YY0] there are more beans showing white, giving you more chance to figure out the white number.

White Type Testing
To test the White Type [C, P, L, R, I] of a No White cat, use any cat with white marks that you know the type of, or Tradewind 28212 [YY10C].
You will have to know the look of all the white types to identify which ones appear, but as 28212 is also an albino you can use the eye colour of any produced albinos to identify the type. Pale Red is Classic; Purple/Pale Violet is Piebald, Pale Blue is Left, Pale Green is Right, Yellow/Pale Gold is Inverse.
28212 is Classic so you will see Pale Red albinos; if you see any of the other colours then that’s the White Type your cat has.
Note: Any cats before ID 89601 will be Classic Type [C]

The Final Hurdle
Okay, bear with me here. This last test isn’t sandbox testing, and it requires you to have recorded the stats of your beans at two points in their growth. This is growth testing. This is math. It will feature my not-cat Asha who I have two points of data for.

I have made a thread with Gathouria which has a calculator for doing all of the math, as well as explaining how it works. I also have a thread where I will do the calculations for you.

We’ll start with an easy introduction, calculating min, max, and median total stats (sum of all stats). (Median is average but average didn’t alliterate).

Average total stats is the easiest, it’s 25% at Young Kitten, 50% at Kitten, and 75% at Adolescent. If you have the stats for a Young Kitten, you multiply them by 4 (25 x 4 = 100); for a Kitten you multiply by 2 (50 x 2 = 100); and for an adolescent you divide by 3 and multiply by 4 (75 / 3 = 25. 25 x 4 = 100).
[bullet]

Young Kitten > stat x 4

Kitten > stat x 2

Adolescent > (stat / 3) x 4

Min and Max (and all other) total stats are slightly more difficult, but there’s still a simple calculation you can use:
(stat / percentage) x 100
This is the basic formula for all of growth testing, it even works for the average, average just has an easier method. When you divide the stat by the percentage you calculate 1%, and multiplying it by 100 therefore gives you 100%.
You find the stat from your cat page. You find the percentage on the growth table here.

For min total stat you use the green percentages. For max total stat you use the red percentages. Average is the pale orange.

As a quick example, we’ll calculate Asha’s min, max, and median total stats.
As a Young Kitten, Asha’s total stats added up to 33.
His min total stats are 33 / 35 x 100 = 94
His average total stats are 33 x 4 = 132.
His max total stats are 33 / 15 x 100 = 220
(Where there were decimals I rounded up for .5 and over, and rounded down for .49 and under.)

That’s the basic math for growth, let’s get into testing for genotypes.
I will have a thread were you can request me to test for you, but for now here are the instructions.
You first need at least two points of data. I have Young Kitten and Kitten.
Then you calculate min, max, and median for both growth points. We’ve already done this for Asha as a Young Kitten, now we’ll do it for him as a Kitten with total stats of 47
His min total stats are 47 / 60 x 100 = 78
His average total stats are 47 x 2 = 94.
His max total stats are 47 / 40 x 100 = 118

Now we already got lucky, in that his min at YK (green) is the same as his average at K (pale orange), which means that his growth pattern is Dip [BC] and his total adult stats will be 94.

Things aren’t always this perfect.
Due to how stats are rounded you may see slight differences of +/-5 between calculated total adult stats at two different points, what you would do is find the pair (or trio if you have three data points) with the least difference between them and then that is your not-cats predicted growth pattern.
For example, a not-cat who went from 27 at YK to 51 at K.
YK min total stats are 27 / 35 x 100 = 77 K min total stats are 51 / 60 x 100 = 85
YK average total stats are 27 x 4 = 108. K average total stats are 51 x 2 = 102.
YK max total stats are 27 / 15 x 100 = 180 K max total stats are 51 / 40 x 100 = 128
The next step here is to look at the gaps; max has a gap of 53; average has a gap of 6; min has a gap of 8. Max has far too great of a gap, so we want to ignore below above the average (orange and red on the table). Average and min have the closest gaps so we want to first focus on their closest growth patterns.

We look at the table again and we see that average is pale orange and min is green, so we want to be looking at growth patterns Early (30% and 55%) and Decreasing (35% and 55%) as they have green and yellow (yellow being in between green and pale orange).
YK Early total stats are 27 / 30 x 100 = 90 K Early total stats are 51 / 55 x 100 = 92.7
YK Dec total stats are 27 / 35 x 100 = 77. K Dec total stats are 51 /55 x 100 = 92.7.
I’ve kept the decimal here to better show that the closest gap, of only 2.7, is in the Early growth pattern, and so we can predict that this not-cat has a growth pattern of Early [A|B] and will have total adult stats of 90-92+ (this is because the number could potentially increase due to rounding in the adolescent and adult stat increases).

Here is a table showing all of the calculations. You can just input the results and compare which are the closest. I still recommend starting with min, max, and median and focusing on the segments that should have the smallest gaps after that. You can also just do the calculation for each colour in each column once and copy paste into same coloured spaces.

[AA] = Very Early _______ [AB] = Early _________ [AC] = Decreasing
[BA] = Arch _____________ [BB] = Steady _______ [BC] = Dip
[CC] = Increasing _______ [CB] = Late __________ [CA] = Very Late

If you have any questions don’t hesitate to ask.
I hope this has helped to understand Not-Cat Genetics

Genetic Testing your Not-Cats With Images

Time for the fun science section again; writing out your Not-Cat’s Genetic String, this time with images to help better visualise what everything looks like

The Easy Part (In green because this is verbatim from the text only version)
You can get the bulk of the genome string from the Appearance Information of your not-cats.
This is Darkfang, a North wind not-cat

This is her Appearance Information

From this we can already tell that she is a Not-Cat [C], she is Northwind [N?], is a Longhair [LL], Black fur [B?F?4], Mackerel Pattern [Y?TT], and has White Bib, Boots, & Belly [Y?5C], (where ? means an allele we don’t know.)

Species- C
Wind - N?
Fur Type - LL
Colour - B?F?4
Pattern - Y?TT
White Marks - Y?5C

The Question Marks [N? etc] mean that we aren’t 100% sure which allele she has, whether two dominants, or a dominant and recessive. This is where genome testing comes in.

The Less Easy Part
Now with Images!!!! From here on we won’t be using Darkfang, we’ll be using a variety of Not-Cats with the perfect genes to display each outcome
To test unknown alleles we can use the Beans Sandbox, in which you combine two Not-cats to see potential beans.
The basic rule for testing recessive or invisible alleles, is to use a not-cat that you have a confirmed genome string for. You also want to preview at least five different bean sets to be sure that there is no recessive/invisible allele.

What if my not-cat is a Null wind?
Unfortunately there is no way to test a Null wind, as they can’t breed so can’t be used in the sandbox. However you can fill in as much of the string from the appearance info (above). Null not-cats also still have a set of colour genes, they are just overridden by the Null genotype, which is what causes the snow colour. So you could have a coloured not-cat underneath the snow colour. The only way to see this is by using a Family Tree on your Null not-cat.

MAJOR DISCLAIMER: There is a very rare “mutation” called the “Pushy North Gene.” Squid has explained it here. In essence, there is an unknown probability (all we know is “very rare”) that a North/South pairing can produce beans with duplicate replica genes of the North parent. (There are rumours that beans born in the South, when we get more locations, could have duplicate replicas pushed by the South parent, but we aren’t there yet). This has a theoretical chance of occurring with all paired allele genes. The effect in sandbox testing is that you may have a pushed bean show up. So far this has been witnessed with Null cats appearing when only one parent has a null allele. I recommended refreshing to see if more appear, because a standard null recessive pairing has a much higher chance of nulls and you will see more quite quickly. Ultimately, just make sure you roll multiple instances before confirming a gene.

Users Tanya, nap, ghost, mayanaz, and tammoratya have been kind enough to allow the use of their not-cats in testing.
DISCLAIMER - Do not go from this guide to contact the owners to breed from or buy these not-cats!

Null Testing
To test for the Null allele in a North or South not-cat (Trade not-cats cannot have a null allele), you use a South or North not-cat with a confirmed null allele.
For North not-cats, use South 747 [SO]
For South not-cats, use North 2509 [NO]
A cat who does carry null will regularly show null/snow beans. The chance is 25% so you should be seeing at least one every roll, but you may get some rolls with zero so roll a few times.

A cat with no null allele [NN] or [SS]

A cat with a null allele [NO] or [SO]

Recessive Longhair Testing
To test for a Longhair allele you can use any Longhair not-cat, or Tradewind 983 [LL]
A cat who does carry Longhair will regularly show Longhair beans. The chance is 50% so you should be seeing at least one every roll, but you may get some rolls with zero so roll a few times

A cat with no Longhair allele [SS]

A cat with a Longhair allele [SL]

Orange and Black Testing
To test a North or South not-cat’s invisible colour allele, you need to use a [BB] or [OO] not-cat.
To test for invisible orange in a black not-cat, use Tradewind 983 [BB].

A black cat with no orange allele [BB] In this test, grey cats count as black

A black cat with an orange allele North [BO] or South [OB]


To test for invisible black in an orange not-cat, use Tradewind 3038 [OO]

An orange cat with no black allele [OO]

An orange cat with a black allele North [OB] or South [BO]


Albino Note: Albinos display no Colour genes so you will have to test both colours. For albinos with both a B and an O there is no way to tell the order, so I generally just go alphabetical with [BO]

Recessive Dilute Testing
To test for a Dilute allele, use any Dilute not-cat (greys or creams), or Tradewind 983 [DD]
If any of the beans result in a dilute not-cat, then your not-cat has the Dilute allele. For this test you really have to know what the colours look like so feel free to also use the cat sandbox to double check colouring.

A cat with no Dilute allele [FF]

A cat with a Dilute allele [FD]

Colour Density in Albinos
Because Albinos don’t display Colour genes, we also need to test for their colour density [1-4]. To test for Colour Density, use any cat you know the Density of, or 983 [BBDD4]. You will have to be able to recognise the colours, or have the cat sandbox handy to double check. The black and grey groupings are easier to distinguish colours than the orange and cream groupings, so I recommend focusing on those (which 983 will make in the box).
Identify how many different colours from one group are produced as beans. 983 will always produce black[F?4] or charcoal[DD4] beans (depending on the Colour Strength, Full or Dilute, of the cat being testing), so we just need to see whether the beans also get Chocolate[3] or Grey[3], Brown[2] or Smoke[2], or Tan[1] or Silver[1]. The palest Density bean produced is the Density of your cat.

A cat with Density 4

A cat with a Density 3

A cat with a Density 1

The circled cat is a density 1 watercolour, obvious by the snow colour. Any bean with snow used in the watercolour patterning means your cat is density 1

Recessive Solid Testing
Solid is a cat with no patterning [NN]. To test for a Solid allele, use any Solid not-cat, or Tradewind 983 [NN].
If any of the beans result in a solid not-cat, then your not cat has the Solid allele.

A cat with no Solid allele [YY]

A cat with a Solid allele [YN]


Albino Note: Albinos also show no pattern. In testing, if your albino makes only Patterned beans they are [YY] (like the first cat); Patterned and Solid means [YN] (like the second cat); only Solid means [NN] (see below)

Albino cat with two Solid alleles [NN]

Pattern Testing in Solids (and Albinos)
If your not-cat is solid (or Albino), they still have a Main Pattern gene, it’s just hidden. To test for their hidden Pattern, use any not-cat with a double gene (Mackerel [TT], Clouded [MM], Spotted [SS], Colourpoint [PP]), or Tradewind 2534 [TT].
Look at the patterns on the resulting beans (you may need to double check in sandbox to recreate them). Using 2534, if they only produce [TT] then your not-cat is [TT]. If they only produce [TT] and [TS] then your not-cat is [TS]. If they only produce [TS], your not cat is [SS]. Producing [TM] and [TP] makes your not-cat [MP], etc etc.

Recessive No White Testing
To test for a No White allele on a cat with White Spots, use any white spotted not-cat with confirmed [YN], or Tradewind 983 [YN1].
Note: You can use an NN cat as long as they are confirmed to be 1 or higher. NN0 will give false results.
If any of the beans result in a not-cat with No White, then your not-cat has a No White allele.
Note: Do not count any bean poses that hide Locket (sleeping, playing). Preview closer to ten times to test more beans that show all white mark options.

N|N vs 0 Testing
To test whether a No White not-cat is [NN] or [Y(Y/N)0], use any cat with [NN] and a number of 1 or higher, or Tradewind 36925 [NN10]
If any of the beans show any white, then your not-cat is a [Y(Y/N)0]. If they show no white then your not-cat is [NN?].
Note: The only way to see if your not-cat is [YY0] vs [YN0] is to look at the percentage of beans that have white in this test. If it is around 50/50, your cat is most likely [YN]. If it is greater than this, your cat is most likely [YY].

N|N White Number Testing
Note: This is for born/fostered not-cats, and any custom or migrated not-cats with ID’s higher than, 11358. Custom/migrated not-cats below this ID are still [NN0].
To test the White number of your N|N not-cat, use any cat with [Y(Y/N)0], or Tradewind 15075 [YY0].
If any of the beans show white then you have a numbered [NN]. Preview the beans to find the highest white number that is produced and that is your not-cat’s number. It helps to recognise all the white markings, or have the at sandbox up in another tab.

White Type Testing
To test the White Type [C, P, L, R, I] of a No White cat, use any cat with white marks that you know the type of, or Tradewind 28212 [YY10C].
You will have to know the look of all the white types to identify which ones appear, but as 28212 is also an albino you can use the eye colour of any produced albinos to identify the type. Pale Red is Classic; Purple/Pale Violet is Piebald, Pale Blue is Left, Pale Green is Right, Yellow/Pale Gold is Inverse.
28212 is Classic so you will see Pale Red albinos; if you see any of the other colours then that’s the White Type your cat has.

A cat with White Type Left [L]

A cat with White Type Right [R]

A cat with White Type Inverse [I]

Take note of the cats circled in Yellow. This is another indicator of inverse white. It may look like an Albino with black eyes, but it’s just a high white Inverse cat hiding a colour mantle (owl or heart)

If you have any questions don’t hesitate to ask.
I hope this has helped to understand Not-Cat Genetics

F.A.Q

Got a question? PM me and I’ll answer as best I can.

Q: When gening a trade winds cat, their wind gene is either N|S or S|N. What's the difference? And for testing no-white, what's the difference between Y|N and N|Y? When doing patterns, taking classic as example, there's either T|M or M|T, how do you know which is the right one? Same with shorthair's S|L and L|S?
A: There is no functional difference in the order of those alleles in those genes. The only genes where order matters are in Colour Group (because the Wind position and the Wind of the not-cat determines what the colour is), and the Growth gene (because A|C is different to C|A)

Q: What does the C on the end of the white marking string mean?
A: The C on the end of the white markings string tells you that these are Classic white markings. There are plans in future to make more variations of white markings, which Squid has said will also affect eye colour (albinos have red).

Q: Do the color alleles have a chance of being B|B or O|O?
A: Yes, Colour alleles have a chance of being BB, BO, OB, and OO. For example, in Trade cats, BB and OO are watercolour colour types, while BO and OB are tortoiseshell colour types.

The Growth Testing Math Ramble [July 2022]
Okay, bear with me here. This last test isn’t sandbox testing, and it requires you to have recorded the stats of your beans at two points in their growth. This is growth testing. This is math. It’s half finished math as well because until I have a Not-cat to to the math on I don’t know how to explain all the math. For now I’ll show you how to get the potential lowest, highest, and average max stats for any bean at young kitten age.

Getting average max stats is the easy part, because you just add the young kitten stats to itself twice.
Take, for example, S’rsh. She has a total stat count of 17, and I’m really hoping she just has slow growth genes. If she was on an average growth, then 17 is 25% of her max stats, we double both to see 34 is 50% of her max stats, and we double those again to find that 68 is 100% of her max stats.
The easy way to think of average growth is to just multiply Young kitten stats by four [17 x 4], or Kitten stats by two [34 x 2]. To get average stats from an adolescent you’d have to divide by three and then times by four. [51 / 3 = 17. 17 x 4 = 68]

When you have a calculator all this is very easy but as we’ve established in my breeding rambles I do not use a calculator.

When we get to highest possible and lowest possible things become a little more tricky.

With Very Late growth, a Young Kitten is at 15% of its stats. So if we take S’rsh again, that means 17 would be 15% of her max stats. Now to calculate this on a calculator you’d do [(17 / 1.5) x 10]. Dividing it by 1.5 gives you 10%, then multiplying it by 10 gives you 100%.
Again, I don’t use a calculator so here’s how I do it:
I multiply 17 by 2, to give me 34 = 30%. I then divide both by 3, to give me 10 and 4/3 which is 11 and 1/3. Then multiplied by 10 which makes 110 and 10/3 which is 113 and 1/3, which is 113.3 recurring (meaning a lot of threes after that .3).
So if S’rsh was a slow grower and had 15% of her stats as a young kitten she would end up with 113.3 total stats.

With Very Early growth a Young Kitten is at 35% of its stats. Which means for S’rsh, 17 would be 35% of her max stats. On a calculator this is [(17 / 3.5) x 10]. Again, the division makes 10% and the multiplication makes 100%.
For me this becomes: 17 is 35%, multiplied by 2, it becomes 34 is 70%, divided by 7 (to get 10%) we get and 6/7. Multiplied by 10 we get 40 and 42/7 which is 46.
So if S’rsh was a fast grower and had 35% of her stats as a Young Kitten she would end up with only 46 total stats.

It’s the same basic technique for discovering stats at each percentage. If you have a calculator you just divide by whatever you need to reach 10%, and then multiply by ten. So if it was 20% you’d divide by two and multiply by ten, 45% you divide by 4.5, etc etc.

I have a basic theory for how you calculate growth genotype, but it is a theory and is yet to be tested.
You need to know two age points and the total stats at those age points.
I’m too tired to fully explain this right now but you’d have to play around with the percentages and figure out which track matches up with the stats that are showing. I’ll get to this when I have some beans to test math on.
