However the problem with that chart is that you are trying to map out the genes of a species we know little about. For example, so far we haven't seen any Faunus with a mix of animal traits, implying that maybe come traits just take dominance over others. So for example, Blake's parents could be a cat and a fox, but the cat genes are just more present. This also shows with tails, as Sun is the only one so far to be seen with a tail in the series. I point this out because Velvet and Blake don't appear to have tails; neither do the White Fang members they fight.

It could also be that the type of Faunus solely depends on their mother or father. This could be a weird example, but it could be like the Pokemon games. In those games, any Pokemon that is in the same egg-group can breed (if one is male and the other female), but the offspring will be the same species as the mother (with one or two exceptions). Going by this, Blake would only have Cat-Faunus if she ever had children despite the type of Faunus her partner was; but her children would be boy or girl Cat-Faunus.

Oh gods, I'm talking about the breeding habits of a species in RWBY! Not again!
