Genetic testing your pets is easy but does anyone understand the results? I think I understand that the green are carried traits and the blue are visible. But what are the other ones and the initials?

Purple text indicates a Hidden trait
If you look in the generator, you can see that each trait has a letter next to it (which denotes trait dominance, closer to A = more dominant, closer to Z = less dominant, with N being the outlier Nothing and most dominant)

Each trait slot is made up of two trait letters, and when bred it's 50/50 which gene-letter the pet passes on in each slot

NN = nothing
NA = Carried A
AA = Visible A, with the second gene-letter also being A
AB = Visible A with hidden B

Take this griffi:

She has Mutation Two: (HI) Skull Regalia
H is the trait-letter of Skull Regalia, I is the gene-letter of Druidic Essence:

So if I bred her, she could pass either of those two traits on to the offspring, even though it isn't visible on her (whether it would be visible or not in an offspring would depend on the breeding partner)

Thank you so much!
