Genetics question about Brown-reds

[tadkerson]

You are going to have to out cross to another breed (OEGB) to get a brown red rosecomb (RC). A person could test cross black RC and determine if they contained the birchen gene but that would take too much time. The large white ear lobes on the RC would be the only major problem with out crossing to OEGB.

You would have to use a brown red OEGB on a female black RC ( these are easiest to find) or better yet a black breasted red . Then cross the offspring and you should get some brown reds. A person will have to hatch 30 or more offspring. Look for adult birds that have some lacing on the breast-they are birchen for sure. The birchens will also be crow winged.

What about using a blue breasted male? Would that work in the same general way??

 

[tadkerson]

Yes that would work but you would have to deal with the blue. You may get some nice lemon blues in the process.

Soo if I mixed a Blue breasted red Rosecomb male to a Blue Roseomb hen I would get some Lemon Blue Rosecombs?

Ryan,

No, you must have a birchen bird in the cross. Lemons are birchen , blue and sex linked gold. They also must have a gene that modifies the gold to a lemon color. You can produce lemon blue males if the male carries the sex linked gold and a sex linked silver alleles.

The females have to carry a gene that modifies the gold to a lemon color. Females can only carry one allele at the S locus and that would be the sex linked gold allele. The cream gene will work to modify the gold. There are most likely other undocumented genes that will do the same for male and female lemon varieties.

Your cross would produce blue rose combs.
