Males are ZZ and females are ZW, that is correct. The W chromosome is shorter and does not carry the silver gene.

I see that this question was asked three weeks ago, and that it's the only question you've asked, so you're probably not gonna read the answer... but I'mma answer it anyway. So. The Z chromosome is not an allelle. A chromosome is a whole big collection of genes, wound together. An allele is a...

Not quite. The chick should have only one copy of ig, and since it's a completely recessive gene, it would have no effect. So S/S+ and Ig/ig. You'd get gold leakage, but even if you bred him to a citron female, only half of the offspring would be citron. EDT: Silver does dilute gold, when...

That is weird.

Thanks!

Good night!

I was reading a lot of stuff doing research for this (I really should be sleeping) but I understand that Sebrights have fertility problems in the males, and the chicks are very susceptible to Marek's. So yeah, I'm guessing barnyard hybrids as well. Yesterday, someone tried to sell me OEGB hens...

This is citron; there are both citron hens and roosters. Are we thinking two different colours, maybe?

ig's not present in most populations. It's pretty rare, and according to one source (can't find it now...) they bred a few Sebrights back to Citron Hamburgs to get it. Crossover happens (during meiosis I, I believe? It's been a while, I'll have to consult my old textbooks) but as I understand...

Just did some research, actually. It's still impossible for hens to receive two copies of a sexlinked gene. If they did inherit it, they'd be roosters. Instead, there's a gold inhibitor gene, represented by ig (Inhibitor of gold. Clever, right?). It's recessive, so for the bird to be citron...

I think this is a good explanation, but feel free to tell me it needs clarification. I'm bad at 'splaining. I'm definitely no "The Moonshiner" (He makes genetics simple.) Roosters carry two "W" sex chromosomes, which makes them male. "WW" Hens carry one W and one Z sex chromosome, which makes...
