also, I would like to add for the sex link thing to be true, males would be the only ones that could be homozygous. assuming it doesn't jump over to the other chromosome

its interesting to hear there are "mistakes" in other animals, seems to fit with what is public right now.

would be nice to have some community statistics. Like are the few homozygous animals male and how often does a male produce a male?

To my knowledge, no one has proven banana and coral glow compatible. Its just the genes are so damn similar, even down to the mystery males, its just suspected they are.
