ok thank you for taking the time to explain it. Yes I am 100% possitive he has two beautifully marked porcelian parents. So hopefully he will pass on the porcelian to a chick or two.Ok I bought a "porcelian" chick last spring, he was nice and sooty as a chick and feathered in as white as a cloud. I still love him, and would like to breed him. I read where white is dominant and can sometimes take over other color genes. So my question is, if I breed him would he pass on the porcelian or white?
He came out of a porcelian mom and dad. I saw the adult birds.
Also I have a black hen and a blue partridge hen, what would his potential chicks with theses hens be?
If you're absolutely sure he came out of two Porcelain parents, then you're dealing with recessive white. That idea fits with his "sooty" chick down as well.
White - both recessive and dominant - is extremely unpredictable. The bird is not genetically white. It can be any color at all - anything from Blue to Partridge - but it's covered with a white coat of "paint". Dominant white could give you some white chicks and/or some of other colors, depending on the hen's color and what color the male is hiding. However, recessive white needs two copies of the gene to make a bird white - so unless you breed him with another white, you won't get white babies. The offspring will carry white, but it will not show, and they will display the result of the male's true color crossed with whatever the hen's color is.
Your male did come from Porcelain parents; so it would be reasonable to assume he is hiding Porcelain. But it's not 100% certain, and because you can't see it, you also can't determine how well marked he is, either.
I have him in with a blue partridge hen and a black hen. I'm holding for some colorful chicks! (just pets and fun!)
