Cinnamon gene in cats what? - briefly
The cinnamon gene in cats is a recessive genetic mutation that dilutes black pigment to a warm, reddish-brown color, creating a distinctive coat variation.
Cinnamon gene in cats what? - in detail
The cinnamon gene in cats refers to a specific genetic mutation that affects the coloration of a cat’s fur. This gene, scientifically known as the b allele in the B locus, is responsible for producing a warm, reddish-brown hue in the coat, often described as a cinnamon or light brown shade. It is a recessive allele, meaning that a cat must inherit two copies of the gene (one from each parent) to express the cinnamon coloration. The cinnamon gene is one of several alleles in the B locus, which also includes the dominant black (B) and the recessive chocolate (b) alleles. The cinnamon gene (b’) is the most recessive of the three, producing a lighter and more reddish tone compared to the chocolate gene. This gene primarily influences the production of eumelanin, the pigment responsible for black and brown colors in a cat’s fur. Cats with the cinnamon gene may exhibit this coloration in various patterns, such as solid, tabby, or pointed, depending on other genetic factors. The cinnamon gene is relatively rare in the general cat population but is more commonly observed in certain breeds, such as the Abyssinian, Somali, and Oriental Shorthair. Understanding the genetics behind the cinnamon gene allows breeders to predict and selectively produce cats with this unique and visually striking coat color.
