![]() ![]() However, no scientific backing suggests that cat colors influence how a cat behaves. Many people think a cat’s color influences their personality, which is why many people are afraid or suspicious of black cats, which have been stereotyped due to unfounded superstitions. Does Coat Color Influence A Cat’s Personality? Orange tabbies are sometimes referred to as their own breed, but they can be many different types of breed, as orange refers to the coat color and tabby refers to the coat pattern. Tabbies can have any coat color ranging from brown to gray, cream, and black. 7 Orange tabbies span many breeds, including the Persian and American Short Hair.Īs we’ve mentioned, all orange cats are tabbies, but not all tabbies are orange. However, the orange gene is dominant, so orange cats can’t be solid colors.Īdditionally, the coat markings are dark and light because of the two dominant genes, which could be O/Y or O/O in cats. 6 Solid-colored cats, like black cats, don’t have the dominant gene instead, they have two recessive genes that prevent the tabby pattern from being expressed. When the agouti gene is dominant, cats have a tabby pattern, and cats don’t have the tabby pattern when the gene is recessive. There’s a separate gene responsible for a cat’s coat pattern called the agouti gene, which can either be dominant or recessive. All orange cats are tabbies, but not all tabbies are orange. ![]() But female cats need fully orange fathers with an orange, calico, or tortoiseshell mother. Meanwhile, males only need red, calico, or tortoiseshell mothers. However, since there are so many possible chromosome combinations, females are less likely to be orange. 5įor female cats to be orange, they need the B gene on both X chromosomes. Ultimately, any cell could end up expressing traits from either chromosome, so it’s rare for females to be orange. 3 This process, called lyonization, is random, so it’s impossible to predict which X chromosomes will be active and express the coat color. 4 Since female cats have two X chromosomes, their body would have to inactivate one of them in every cell to not express double the amount of the X-linked phenotypes, leaving only one active X chromosome in female cats. However, the orange gene must come from both parents instead of only the mother. 3 Because males only need one copy of the orange gene from the mother, they’re more likely to be orange than female kittens. Males only have a single X chromosome, which can carry the orange or black coat color gene. How males get their coat color is much more straightforward since males have a Y chromosome that can’t carry the orange gene. The B gene is in the X chromosome, where a male only has one, and a female has two. The gene B produces a red pigment called pheomelanin, a dominant trait. The orange color coat is sex-linked and found on the X chromosome. These rare defects usually cause sterility in male cats but not in females. However, calicos can be male and orange cats can be female. Since female cats get two X chromosomes, one from each parent, they could have both the black coat color gene and the orange coat color gene. 2Ĭalico cats are almost always female because of these same genetics. Since the X chromosome has the orange coat color gene, and male cats only need one X chromosome from their mother to become orange, most orange cats are male. Male cats inherit the Y chromosome from the father and an X from the mother. ![]() Female cats get one X chromosome from each parent.
