If you are talking about color sex linked, no. The reason you can get sex links by colors is that the hen passed on certain traits to her son and not to her daughters. For example, a hen with a sex linked barred gene will give the barred gene to her sons but not her daughters. If you breed her to a rooster that does not have a barred gene, then the offspring will be sex linked. There are certain restrictions to this since you have to be able to see the barring in the male chicks and there are only certain color combinations that work.
So if "B" represents the dominant barred gene where if the bird has this gene the chick will be barred and "b" represents the recessive not barred gene where the chick will not be barred if it has this. The parent rooster has two genes, bb, so it is not barred. The hen has a single gene B, since it is a sex linked gene in the hen. The hen and rooster both give a gene to the male offspring, so the male chick has Bb. It will be barred since the B for barring is dominant. The female chick will not get a gene from its mother, so it will only get a b gene from the father and it will not be barred.
Now, if you cross the offspring, the Rooster has Bb and the hen has b. The rooster will give half his male offspring a B gene and the other half a b gene. He will also give half his female offspring a B gene and half a b gene. The hen will give a b to her male offspring and nothing to her female offspring since it is a sex linked gene. So half the male offspring will be Bb and barred and half the male offspring will be bb and not barred. Half the female offspring will get a B from the father and nothing from the hen and be barred. Half the female offspring will get a b from the rooster and nothing from the hen, so it will not be barred. The sex link is lost after the first generation.
Different genes are used but the principle is the same to get a red sex link. There the roosters are off-white and the female chicks are red.
Tadkerson does a better job explaining it in the link I gave in the previous post. Hope this helps.
BridgetC, it will be interesting to see what Belt crosses to get their red sex link.
Thank you rirdgerunner. I might need to reread this another time or two to get it all what you said. LOTS of GREAT info. thank you so much.
