Are rays the same as most animals?
If the ray is albino, any offspring would be 100% het for albino, but unless the mate holds the albino gene, you wouldn't get any visible albinos.
Breeding the albino back to a het albino would give you a mixture of visible albinos along with non visible which carry the gene?
I bred snakes for years, and know how the mutations and genes work with them.
I assume it's the same for all other animal's, but not sure.
