The white color, however, is not linked to sex chromosomes. Females have two X chromosomes, so they can have genes for both black and orange and thus create tortoiseshell patterns. Males only have one X, so a male cat will only be either black or orange. The terms tortoiseshell and calico are mainly used to signify the color patterns of the cat’s fur and are not considered a breed. In other words, for these colors to show, the cat must have the X chromosome. Tortoiseshell cats are orange-and-black cats resembling the body patterning of a tortoise, while calico cats have three colors in their coat (orange, black, and white). The information for black and orange colors are in the X chromosome. Depending on the combination, the cat can be male or female. It is important for cat owners and enthusiasts to understand the differences between these two patterns, as they can indicate certain genetic traits and health concerns. The main difference between Tortoiseshell cat and Calico is that Tortoiseshell cat has a combination of only black and orange on its coat while Calico has additional white patches due to the piebald gene. Female cats, like female humans, carry a XX chromosome. The mother always gives an X chromosome, and the father can give X or Y. Calico cats have a white base coat with patches of orange and black, while tortoiseshell cats have a base coat of black with patches of orange and sometimes white. Tortoiseshell and calico cats are almost universally female because the gene that produces the coat color is sex linked. Cats, like all mammals, have two sex chromosomes: X and Y. Sex chromosomes are the ones that determine the sex of the cat. If you think that your cat has a particular attitude, you should definitely check out this article for a. While tortoiseshell and calico cats are very similar, they’re not actually the same thing. However, it’s a rather clumsy descriptive term. Being a Calico owner, I can confirm that my cat shows signs of Tortitude or Calico Attitude. You’ll often hear tortoiseshell and calico used interchangeably. The term tortoiseshell calico cat usually refers to a tricolor female cat with patches of black, red and white fur. Cats have 38 chromosomes: 19 are provided by the mother and 19 from the father. Although not completely scientifically based, it is believed that both Torties and Calicos have a very particular personality. Therefor, the color and pattern of the cat's coat is a feature that is linked to its sex.Ĭhromosomes are structures found in the nucleus of cells that contain all of a living organism's genetic information, that is, its DNA. The color and pattern of a cat's coat depends on the animal's genes more specifically, the information for hair color is coded into the two chromosomes that determine the animal's sex. ![]()
