Extended black, hackle, shoulder and saddle of the males may leak groundcolor (eg red) depending on unknown absent genes. Search our database of over 13360 posts with up-to-date information from our experts and veterinarians. However, it does depend on which parent is carrying the dominant gene.

Most of the dominant genes do not help, but one sex linked dominant and the interloper's single comb can. )To determine the genetics of the offspring, one takes the four possible combinations of the genes of one parent with the genes of the other parent.
