Assuming coral glows and bananas are the same, this is what I herd from a reliable source.
At least the coral glows, when a female coral glow lays eggs, you get the expected 50/50 ratio you would expect to get from a heterozygous animal and getting the expected 50/50 ratio of male to female.
The problem comes when breeding male coral glows. When you breed a male coral glow to something, it appears all females are coral glows and all non coral glows are males. This could easily be explained by a sex linked trait, since males are assumed to be the same chromosome animal (unlike humans which the female is)
The problem that kills the theory is that very rarely, the male coral glow will make another male coral glow. The ratio is so low, it doesn't really seem to make much sense with what we know right now.
so thats all I know and we're stuck at "we don't have a clue whats going on" Unless someone has more info?
