There is a gene that dilutes both the Black [Eumelanin] Pigment and Red or “Chestnut” [Phaeomelanin] pigment. This gene called the Cream gene, is typically symbolized by the letter Cr. The Cream gene has Incomplete Dominance, meaning that having one copy of the gene looks different than having two copies of it. Having a single copy [Crcr] of the cream gene will lighten the coat. Having two copies [CrCr] of the cream gene lightens the coat, skin and eyes.
