The two major pigments that impact canine coat color are eumelanin (black pigment) and phaeomelanin (yellow/red pigment). This dog will pass e on to 100% of its offspring. The coat color of this dog will be yellow/red (including shades of white, cream, yellow, apricot or red). This dog carries two copies of e which inhibits production of black pigment. Interpretation: Black (carries yellow/red) This dog will pass E on to 50% of its offspring and e to 50% of its offspring, which can produce a yellow/red coat (including shades of white, cream, yellow, apricot or red) if inherited with another copy of e. However, this dog's coat color is also dependent on the K, A, and B genes. This dog carries one copy of E and one copy of e which allows for the production of black pigment. This dog will pass E on to 100% of its offspring. This dog carries two copies of E which allows for the production of black pigment. The E Locus (Yellow/red) coat color test reliably determines if a dog has one of the following genotypes at the E locus: E/E
