Chinchilla Persian cats may be silver, golden, or blue, as well as combinations of these colors. The chinchilla coat pattern is found in a few breeds, including the British Shorthair, Persian, and Siberian. When tabby cats carry the melanin inhibitor gene (I), they appear nearly pure white with a sparkling silver effect on the tips of the coat, creating the chinchilla pattern.
The dominant allele of this gene suppresses eumelanin production, which keeps the base of each hair light, allowing pigment only on the outer half of each hair shaft. In order to have the chinchilla pattern, a cat must carry the melanin inhibitor gene (I/i).
The chinchilla pattern occurs in several breeds, such as this silver chinchilla Persian.Ĭats with the chinchilla coat pattern, named for the small rodent with a similar coat pattern, have a light-colored base coat with the outer edges of each hair tipped with black.

The black and red genes can also be influenced by other genes, causing dilated colors, such as silver, gray, blue, cream, and fawn. Other colors such as chocolate and cinnamon occur when cats have recessive versions of the black or red gene. Red (orange) occurs when a cat has a dominant version of the red gene (O). Black occurs when a cat has a dominant version of the primary gene for coat color (B). The two basic colors in cats are black and red, caused by the gene for black (B/b/b1) or the gene for red (O/o). Alleles can sometimes cause different phenotypes (observable traits), including different colors or patterns. An allele is simply a variation of a gene. Some genes have slightly different forms, called alleles. A dominant gene overrides a recessive gene two copies of a recessive gene must be present for that trait to occur. Genes come in pairs, one from the mother and one from the father. The topic of cat color genetics is extremely complex, but also fascinating! In a nutshell, different coat colors and patterns are the result of the genes a cat is born with and the way they are expressed. Explore the world of cats, and you’ll see a rainbow of beautiful colors and patterns, including brown, black, white, cream, gray, silver, orange, lilac, bi-colored, calico, tortoiseshell, striped, spotted, smoke, and colorpoint.Ī cat’s coat color and pattern are determined by their genes.
