Hi all! I was wondering the genetic results from crossing a chocolate roo to a Jubilee hen. I just wanted to see if my assumptions are correct as far as possible offspring.
Jubilee is a variant of the mottle gene, which is recessive. Thus no mottling would be passed to the offspring, but they would all be split to mottling. Chocolate is a sex linked gene, so father will pass to daughter, and the sons will carry chocolate but will not show it until crossed with another chocolate or split to chocolate.
Soooo- offspring should be 25% chocolate pullets, split to mottle. And the rest of the offspring would be black orpingtons, split to chocolate and mottling. Is this correct? Thanks in advance for any corrections. I’m trying to learn!
