I could be wrong about this, as I am not the most knowledgeable about the gene notations, but I get the sense that certain genes are not "shown" on their page if both alleles are like... the "default" maybe (not sure what makes it the default). Like, for example, if hom recessive DP (as in, no DP) is the "default", horses which are hom recessive DP don't have a line in their genetics page which shows "DP:-/-". They just don't have it at all, unless they have at least one copy.

I think the same thing is happening here with pangare. It isn't showing because she has 2 copies of (uppercase)"P". I think it only displays that information if the horse has one or two (small)"p"s.

This horse is p/p

Yeah I follow what you're saying. The way they have Pangare in the game is odd. The game says (P) has an effect, and (PP) my have more of an effect (at random), but that (pp) does not have an effect. So In this case is (P) considered the default and (p) is the mutation? I have horses with (p) that look like they have Pangare, but not to the extent that you would realistically expect to see it. From the examples in the Genetics Guide, it appears rather subtle so I'm not sure if what I'm looking at is Pangare.

the genetics guide is your best friend for this stuff :)

Okay, here's what I think is happening. What you're calling 'default', the gene that's represented as -, is the wild type. For a gene like pangare, the wild type is not notated when it shows up, because that is the 'default'. The mutated form is noted when a horse has it, because that's the 'changed' form. The gene that switches pangare off is the mutation. So -/- means there is no mutations there, the horse is homozygous for the wild type, the 'original form' of the gene, if you will, which in this case is pangare. -/p or p/- means that this horse has one non-mutated pangare gene and one mutated no-pangare gene, and p/p means there are two mutated genes and no wild type gene. It doesn't show which gene is active, it shows the little p because it's the gene that's different. I think that's the reasoning, anyway. Flaxen is the same way: f (flaxen) is the mutation, rather than F (no flaxen) which is the wild type, so f is the one that's noted on the gene testing results.
Personally I'd prefer if it showed the notation for all the genes, no -'s at all, but this notation is modeled after how real life gene testing labs notate it
