![]() Lilac is dilute chocolate and bears the same relationship to brown as blue does to black. Since the B gene is dominant over the locus, cats heterozygous for it ( B/b or B/b l genotype), carry chocolate or cinnamon gene but it cannot be recognized based on phenotype. ![]() The chocolate (b) allele is dominant over the cinnamon (b l) allele. Two mutations of the B gene have been identified, b (brown or chocolate) and b l (light brown or cinnamon). Chocolate is frequently referred to as a rare color, but it is quite common in purebred cats, especially Orientals and British Shorthairs. The brown coat color ( b) is a variation of black ( B) coat color and is caused by a mutation that leads to reduced amounts of black pigment which causes them to appear brown and is recessive to black. You can view more beautiful pictures of brown cats in our article “ Why are brown cats rare?“. The British Blue, Russian Blue, Korat and Nebelung are the most well-known breeds with blue coats, but the color can also occur in mixed-breed cats. Black and red are dominant, and therefore only one copy of the gene is needed for the cat to show these colors.įirst, let’s look at relatively rare colors:īlue (grey) is dilute black, the color is chemically black (eumelanin), but melanin granules clump in the hair shaft resulting in colorless areas which allow more light to pass through the hair and lightening the color. Every other coat color is a deviation of those two colors. There are only two true colors in cats, black and red.A dominant gene overrides a recessive gene, and two copies of a recessive gene must be present for that trait to develop. Genes come in pairs, one from the mother and one from the father, and can be dominant or recessive.Each chromosome DNA (deoxyribonucleic acid), which contains the instructions an organism needs to develop, live and reproduce.Cats have 19 pairs of chromosomes, which are inherited from the mother and father. ![]() Before we look at our beautiful selection of rare cat colors and patterns, let’s review a few interesting facts about cat genetics: This explains why some cat colors and patterns are rare while others are fairly common.
