do I have data on whether different species have different genes, and thus are affected differently by genetic conditions? I mean, it's just sort of inherent to the concept of species, no? I guess as a specific example, I could say that the rate of melanism in humans is none, and the rate of melanism in some other species is not none, as evidenced by the fact that the concept of melanism exists, therefore melanism doesn't occur in all species at the same rate
