Happy New Year, @Jack07
All joking about elephant birds and chickpeas aside, I think we got sidetracked with recognizing split black shoulder chicks, and never gave you a proper answer to your question about adding in cameo genes.
I am definitely going to need @AugeredIn to help with this, because the last time I tried to explain sex-linked genetics, I mangled it badly.
I think there are two important pieces to the discussion. First, the inheritance of the sex-linked color itself, and second, the effect of crossing the sex-linked colors with the normal, or non-sex linked colors. There was a discussion about this recently, so I will try to find it again. I think my eyes glazed over halfway through the technical portion and I never finished reading it last month... that hardly ever happens
Let me start by asking a question, do you already understand the inheritance of sex-linked colors? Or should we start with that part of the explanation first
I apologize for my part in derailing the conversation, and hope you had a wonderful holiday season.
