Cornish Lacing genetics

[Alex_Zurago]

Jubilee Cornish are supposed to be double laced, just like a Dark only with the black reduced by two copies of dominant white. Because of the hen's similarity to White-laced Red they have been bred as WLR and almost went extinct. The roo has white everywhere the Dark is black, thus white neck and tail. WLR has red neck and tail single-laced with white.

He might try Silver-laced Wyandot for a cross to introduce silver into Blue-laced Red, since they are supposed to be single-laced and carry the black gene. They have a different type comb and will make the offspring have a walnut comb, but this is a better option than a single comb, which is recessive and very hard to eliminate. Also the Wyandot body type would be less difficult to overcome than any of the other breeds that I can think of. He would need to use the Wyandot roo since the silver gene is sex linked on the male chromosome.

Since it's sex linked would he just inbreed the F1s to get Homozygous for it on both sexes?
