What you say is kinda right but I'm sure the color doesn't need to be on the sexual chromosomes, at least not entirely. Males could have a part of them on the Y chromosome that gives the last part of genes that changes the color. But in the case of a female it could just not be on the X chromosome giving the color the species normally has.

The problem lies specifically in the female offspring as it has two different X chromosomes one of Subspecies 1 and one of Subspecies 2 both having different genes. In the end it would be the same like with each other chromosome having two different ones making it a mixture or having one dominant and one recessive gene. But I guess the males of all subspecies have this dominant gene what means that the females have all recessive genes. So the mixture is more likely.

About the amount of chromosomes... yeah, I didn't think too much about it. Just take it in with the example of the hair. ^^' Though that there are many other chromosome pairs in the body of Rathalos cannot be denied so the argument isn't invalid.
