Genetics Question

[lilmillefleur]

But remember its not auto-sexing because the sex link wouldn't breed true. You'd only have split and homozygous black roosters. So it would only work for that one generation.

The chocolate gene itself is sexlinked. If a chocolate rooster is bred to a black hen it produces chocolate hens and black roosters.

The Dun gene is another gene that can make chocolate chickens but dun is not sexlinked. I guess you need to know what you're working with. If you have chickens that are working with the chocolate gene it can be sexlinked.

Also** If anyone wants to know a way I easily sexlink non sexlinked chickens is this:

If you breed a rooster that has black, slate, or blue legs with no white or yellow color on the bottom their feet and breed that to a hen with yellow legs it produces sex linked chicks.

The hens have darker feet while the males have while soles or white legs. It depends on the color of the chicken tho. If the chicken is white the hens will have blue/green looking legs while the males have all white legs. If the chicken is black or has a lot of melanin such as black/choc then all the produced chicks will have black legs but the males will have white on the bottom of their feet while hens will have black on the bottom.

This is all caused by the Inhibitor Dermal Melanin gene that determines the color of the chicken's feet but the gene is also sexlinked. This is how I produced sex linked chicks from almost all breeds. White rock Hen? and Blue Amerucauna Rooster? That is sexlinked buddy.

Glad you're interested. It is a Cuckoo Watermael. Not available in the US, only in Europe. Unfortunately.
