Feline Dilute

The dilution gene (d) in cats has been shown to be a gene called MLPH, which is an abbreviation for melanophilin. This is the same gene and protein that is responsible for dilute colors in the dog. In cats, there has been just one mutation identified which results in dilution of black pigment to blue or grey. This is a recessive trait, so it is possible to carry dilute (Dd) and not show it, and any dilute kittens must have inherited one copy of "d" from each parent.
