When dogs breed, the mother and father each randomly contribute one allele from each locus, giving each allele a 50% chance of being passed on to the pups. One of the alleles at each locus is dominant and determines the traits, like coat color, portrayed in the dog.

How do you know what Colours your dog carriers?
Genetic testing is the only way to be certain of dog coat color genetic heritage. In our offer you can find available genetic tests for dog coat color, which can be individual tests for specific locus ( A locus, B locus, D locus, E locus, EM locus, K locus) or panel, which includes testing for all loci available.
How do you breed a dog's coat color?
The “E/e” dog passes on E to half of its offspring, and e to the other half, the latter of which can produce a yellow/red coat if inherited with another copy of e from the other parent. Because the “e” allele is recessive, a dog must have two copies of it to express the yellow or red coat color.
