Pet Cats
Calico cats are also called calico cats, and tri-haired cats refer to cats with black, orange and white colors mixed on their bodies. They are also called tortoiseshell colors and are officially called " Tortoiseshell white cat”.
There are only two colors that can control the color of a cat: yellow and black. White is not the color of the cat, but the albino gene acts to prevent the cat’s original color from showing up. The original colors of all cats are only three possibilities: yellow, black, or yellow-black. The ever-changing cats we see are due to the combined effects of other genes that can control color.
The color of a kitten can only be inherited from its parents. It cannot skip the parents to inherit the color of the previous generation. And because the genes that determine black and yellow are sex-linked inheritance and are located on the X chromosome (the white gene is on the body chromosome), Therefore, male cats cannot inherit their father's color, but female cats can inherit one color from each parent. In this way, regardless of the color white, male cats must be single-color, and female cats must be single-color or bi-color.
Also because of chromosomes, the vast majority of calico cats are female. However, in a small number of cases, due to an extra X chromosome or chimerism, tricolor male cats occasionally appear, with a probability of one in a thousand. They generally have genetic defects and have no breeding ability at all.
In Japan, because male calico cats are particularly desolate, they are regarded as a sign of bad luck. The male cat Shamisen that appears in the masterpiece "Haruhi Suzumiya Series" by Japanese novelist Tanigawa Ryu is the Sanhua male cat.
