The tricolor cat, also known as the tricolor cat and hawksbill cat, is also known as the tricolor cat and the printed cloth cat. It refers to the black, orange and white cats, also known as hawksbill cat.
origin
Because the genes that determine orange color and non-orange color are located on the X chromosome (the genes that cause white color are located on the autosome), and female cats will undergo the process of X chromosome deactivation during embryonic development, some cells will show the characteristics of paternal X chromosome, and some cells will show the characteristics of maternal X chromosome, so if the two X chromosomes of female cats have orange and non-orange genes respectively, The coat color of some blocks will be orange due to the inactivation of X chromosome with non-orange gene, and vice versa.
Because under normal circumstances, only female cats have two X chromosomes, most tricolor cats are female.
In a few cases, male tricolor cats will appear due to more than one X chromosome (Klinefelter’s syndrome) or chimerism, and generally have no fertility; Because of the scarcity of male tricolor cats, they are regarded as a symbol of luck.
The orange cat, also known as the orange cat, is a common coat color among mixed breeds of cats. Adult male cats usually weigh over 5 kilograms and female cats weigh over 4 kilograms.
There are more male cats in orange cats (about two-thirds of them, the gene that determines the color of cat’s hair is sex-linked inheritance), and the color of cat’s hair is usually divided into two types: full orange and orange white. All orange cats will have light white stripes on their bodies, and only a few cats will show white on their bellies. The orange and white cat has large orange patches and white fur. Male cats are usually all orange, while female cats are mostly orange and white.
Tabby cat It refers to a cat with stripes, dots or swirls, usually with an “M” mark on its forehead. Tiger-spotted cats are sometimes mistaken for a kind of cat. In fact, similar markings can appear on many different kinds of pure or mixed cats. Tiger spot is a natural feature, which may be inherited from the African wild cat, the ancestor of domestic cat.
Because tabbed cats are a common type, some people assume that medieval cats already have tabbed cats. Then, a writer thinks that this is not true, at least in England. In the middle of the 17th century, John Aubrey, a curious archaeologist, noticed that William Laud, the Archbishop of Canterbury, was a “cat lover”, and that “there are often some Cyprus cats around him, that is, the so-called tabby cats”. Then he said, “I do remember that the average English cat is white.” Now these features have been basically lost.
White cat, all white, with short and thick hair. The white cat with blue eyes is the so-called “white cat”. White cats are born with inner ear defects, which can cause deafness, lack of pigment in their eyes, are vulnerable to light damage, and are sensitive to light. The cat who often hears yin and yang eyes is the “half white cat” cat. There are no white cat defects, but have beautiful eyes with different colors.
Black cats are all black, thick, short and shiny, and often have tiger stripes on their fur, but they are easy to be ignored because of their dark body, and some white hairs are easy to grow on their stomachs.
