Guide on Sex-Linked Mutations

Well a banana male to an unrelated female isn't going to be het for anything. Either it will be born a banana or a normal.

Randy, I think I might have found the thread you were talking about. A male banana to female pinstripe produced a male banana...

So this is at least one instance where the offspring do not follow the expectations for a Z-linked mutation. I'd really like to see information on the parents of the rest of the male bananas and coral glows out there. I know there aren't too many.

Thanks, that wasn't even a year ago and I'd forgotten already. Somewhere there was another thread with info from someone close to the NERD breedings. Maybe they are Z mutations that end up being recessive in males and co-dominant in females and the few exceptions are evidence of freaky ball python genetics?
