What exactly is the genetics on coloration of Jersey giants

[Savannah.e.c]

I have way to many rosters so I am thinning out my flock I want to keep my white Jersey giant roo but he is too mean so I want to keep his son a white and black Jersey giant cross but I wanted to know if the white is ressesive if I was to put him over a white hen what might the babies look like cause I love my white JG so I want to be able to breed more in the future.

IDK the genetics of JGs but I know a bit about white.
Is his son black? If he is and his dad was white then yes white JGs are recessive white.
If that's the case and you breed the son to whites then expect half the offspring to be white and half to be black but carry one gene for white just like your roosters son.
If you breed him to his black split to white daughters then 1/4 would be white.

If the son is black, this prove that your line whites carry only the Recessive White gene, which is how supposed to be. White JG should be recessive white.
So when you breed your "son" with white hen they will produce 50% white babies.
Hope I was able to explain it.

White Jersey Giants are recessive white. They are also supposed to be silver base color. Your white and black cockerel could be black, expressing silver leakage which would make him a poor choice for a breeding program.

I'm reading it as the son is a white Xs black color cross.

I read it as the son is a mixed breed from the White Jersey Giant rooster and is black and white in coloration. OPs wording is a bit confusing.

Hmm now I can see it meaning either. And when they say a white hen does that mean a white JG hen or just a white hen?
If the son is a cross breed then he isn't going to produce white JGs so a breeding program would be out the window.

Pictures are so helpful with this sort of post as it can help us sort through any imprecise wording used by inexperienced folks.

In that case, you should be posting pictures all over the place. The OP posted clearly. She said she wanted to replace her White Jersey Giant Male, with his son that was the result of a cross with a Black Jersey Giant female. The OP wanted to know if the son would produce White offspring when bred to a White Jersey Giant female. Everyone understood until you got involved. You have so much to learn. Since you must have missed it, you shoukd really ask more questions, and make fewer statements. You are really messing up inexperienced people like yourself. If you are interested on poultry, find someone with experience and learn from them. Then maybe you can try to offer advice to others. You seem to offer advice to people who already know more than you do.

How would it be a mixed breed if the bird is the result of mating birds of different varieties within the same breed? Mixed breed would involve mating birds of different breeds. Be careful with your imprecise wording. You should use pictures.
