color genetics question

[minihorse927]

Ok, I know what I get if I breed a chocolate rooster over barred hens, what do I get if I breed a barred rooster over chocolate hens?

Anyone?

Hi Minihorse927,

I am not an expert at all but may be able to give you a little more information.

The barring gene is sex linked. Males carry 2 copies (in purebreds--in mixed breeds they can of course only have one copy) and the females carry one. So if you breed a barred male (if he is pure and carries 2 copies) both chicks will inherit one copy of the gene and will be barred.

Here is a synopsis of the Chocolate gene found on http://www.hpbaa.com/Genetics.html :
Breeding Poultry With the Recessive Chocolate Genetic:
Chocolate to Chocolate = 100%
Chocolate Male to Black Female = Chocolate Females & Chocolate Split for Black Males.
Black Male to Chocolate Female = Chocolate Split Males & Black Females
Chocolate Split Male to Chocolate Female = 25% Chocolate Hens, 25% Black Hens, 25% Black Cockerals, & 25% Chocolate Split Cockerals
Chocolate Split Male to Black Hen = 25% Chocolate Hens, 25% Black Hens, 25% Black Cockerals, & 25% Chocolate Split Cockerals

There is also a nifty chicken genetics calculator where you can put in and change variables of the genetic makeup of the roo and hen you are using (provided you know them) and see what the offspring will look like: http://kippenjungle.nl/kruising.html

What is said here is correct. If the rooster is barred carrying B/B genes for sexlinked barring all off spring will be barred and offspring will be carrying chocolate but not showing it.

thank you both. I thought that was correct. I'm working on chocolate barred standard cochin and trying to figure out which is the best way to breed as I can go barred cochin roo over choc orp hens or choc orp roo over barred cochin hens.

Sending you a PM with the route I would go.

The question is choc rooster over barred hens. Daughters will be choc; sons will be barred (one copy) and split to choc.

Your answer was for a barred cock over choc hens.

I thought I got the question right? Minihorse927--do you need further clarification?

we're all good now. I was trying to figure the bestway to work on chocolate barred cochins.
