So I heard (and to my understanding, I just want clarification) that if two cats can have white beans in the bean sandbox, that means they both carry null? Like these two:



The genetics are still quite confusing to me, admittedly!

@rubeofkubic
Those are nulls, yep! Here's a bit of an explanation:

Nulls (O) can only be produced by crossing a North (N) and a South (S) wind cat. Trades cannot carry the null gene as to be a trade you need both a North and a South allele (N|S or S|N; order doesn't matter). Norths can be N|N or N|O and Souths can be S|S or S|O. Nulls are O|O as it is recessive.

Putting it all together, what this means is that in order to produce Null offspring, the parents need to be N|O and S|O. Crossing a, say, N|O with an S|S will only make South and Trade winds as the combinations are: N|S (trade), S|N (trade), and S|O (South, but carries null!).

In short: your kitties are N|O and S|O respectively, meaning they carry the Null gene and can make Null offspring with each other!

@Nae - Oh wow, thanks so much! I'm working on decoding/predicting my cats genes for fun, and I want those two to be a pair anyway, so that's some good luck!
