A mutation in melanophilin (mlph) causes clumping and uneven distribution of pigment granules in the hair shaft, producing dilution of all coat colors The presence of the dilution gene (d locus) can convert these colors to blue, lilac, or fawn, but the primary distinction among black, chocolate, and cinnamon remains governed by the b locus alleles. Dilute is caused by the deletion of a single base (c.83delt) resulting in disruption of the mlph protein product.
What is a dilute coat The pigmented cutaneous and ocular tissues of maltese dilution and control cats were examined and compared by light microscopy. Dilution is caused by a single base deletion 1 bp in the melanophilin (mlph) gene.
In cats, it affects both eumelanin and phaeomelanin fairly equally The two alleles are d (full color), and d (dilution) Dilution modifies all the self colors we've covered so far into their dilute counterparts. Barrington brown is a recessive browning gene that dilutes black to mahogany, brown to light brown and chocolate to pale coffee
It is different from the browning gene and has only been observed in laboratory cats. There are a number of genes that contribute to the colour and the pattern of colour seen in the cat These genes can be grouped into four levels of function Genes for basic colours, including colorpoint (locus c), agouti (locus a), orange (locus o) and locus e.
The pigment granules are clumped and distributed unevenly along the hair shaft, resulting in a clear color. What a cat’s coat looks like is determined by key genes that dictate the fur’s color, pattern, length, and texture Genes are like blueprints—they spell out how big they will grow, what kind of fur they will have, what color their eyes will be, what color the coat will be, and much more. The maltese dilution is an autosomal recessive trait of cats that dilutes black cats to blue, and orange cats to cream
