Columbian Color Pattern

Date sort Score sort
The columbian primary color pattern in the light brahma is due to the following genes: columbian, brown and silver. The genotype of the columbian pattern is eb/eb, Co/Co and S/S for a male and S/_ for a female. There are genes called restrictors that remove the black from the male and female and the columbian gene is one. The columbian gene leaves black in the neck hackles and saddle hackles, and leaves some black in the wings and tail. The restrictor Db removes black from the hackles and other areas of the body. You can have a columbian like patterned bird but the bird will have a different restrictor other than columbian.

Hey, Tim, thank you so much.

It's really a treat to have another contributor here who really knows his genetic stuff. Glad to have you aboard.

And I hope you've voted in favor of having a separate topic in the index for "Genetics"....hint, hint, hint....

You'll have to breed in something else to bring in the genes. And then you will have to hatch a lot and cull heavily. The barring gene and dominant white will make things even harder. You would be very lucky to manage breeding true within 10 years.
