Yes and no. 50% of the male offspring will have two copies of the barring gene, like a 'purebred' will. The other 50% of the males will only have a single copy of the barring gene. And about 50% of the females will have a barring gene and look like a purebred. But the other 50% of the females will not have the barring gene at all.So if you bread a sex link cock to a barred rock hen would the offspring look like regular barred rocks?
Thanks for that!The main clue is the Barring. The Barring gene is sex linked. To explain it in a horribly oversimplified way, the Barring gene can exist in two copies in males but only one in females (because chromosome reasons). Genetically speaking, a Barred bird is a Black bird with white Barring overtop. Two copies will have a lot more effect over the black background than one copy; and as such, birds with two copies have an overall much lighter colored appearance than birds with just one copy. Hence, in a purebred Barred Rock, males (who have two copies) are much lighter colored than hens (one copy). A male who is dark-colored like a hen cannot be a Barred Rock (or any other barred bird), and instead must be a cross. In this case, the red leakage in the wing bows was the giveaway that they are Black Sex Link males. Black Sex Links are hybrids of Production Red cocks over Barred Rock hens. This produces solid black females and single barred males (one copy). Both have red leakage from the Production Red parent, in females this red shows in the hackle and breast, in males it is seen in the hackle, saddle, and wing bow.
