I thought barring was sex-linked

[cukooformarans]

Our cukoo marans rooster bred a silver phoenix game hen. When the two babies started showing their barring, I thought they were both hens. (They are the dark barred of a cukoo hen as opposed to the light barring of a cukoo rooster, as well.) They started crowing. What's the deal?

(Two copies of barring makes a barred rooster and one copy makes a barred hen, right? Do silver phoenix carry barring? I should say that we bought the silver phoenix as a baby, and since game type hens are brown, I'm wondering if she may not be a silver phoenix?)

barring indicates a cockerel on sex links

I cuckoo or barred roo will pass the barring to 100% of the offspring, UNLESS he only has one copy. All the roos from that cross will be like a sex link with only one copy.

First, barring is sex-linked, but it is only when the MOTHER is barred that you can pre-determine the gender of the barred offspring. Barred hen gives barred sons and not-barred daughters. A barred father passes on his barring indiscriminate of gender. If he has two copies, all his offspring will receive a copy. If he has one copy of the gene, about half his offspring will receive it, and there will be no gender preference. Equal numbers of sons and daughters will inherit it if enough chicks are hatched.

Second, all game hens are not brown. They come in as many different colours as do game cocks; however, they are not as generally colourful as are the males.

Do you have photos of all the birds involved?

Ok ... I thought that roosters had to have two copies to show barring and hens had to have one, so I had it backwards?? I have sold or eaten the roo- he was an ordinary cukoo. I don't have pics of the others, but I could take some. The young cockerels look just like a barred game. They are starting to grow some tail feathers that had me suspicious even before the crowing began. They are 3 months old.

Of the game varieties that I have seen around here, most of the hens are variations of brown except for one or two. I am sure there are tons of others.

Thank you so much for answering, everyone!

Barring always shows, unless all pigment is turned off by white. One copy looks different than two copies, which is how you can tell boys from girls at hatching. (Assuming pure barred.) Girls cannot have two copies; their chromosomes only have a place for one. Boys can have one or two copies. If only one copy, their barring pattern will look like a girls.

males with 2 copies are paler than the females with 1 copy.

In this cross, if the dad had 2 copies, then every offspring will have only 1 copy of barring as long as the mother had no barring. with only 1 barring gene the offspring, male and female will look alike.

Thank you so much! I understand it now!
