How to classify cats according to their fur color

       It is influenced by two or more pairs of bodies.

       Red ¡ú yellow (enzyme a) ¡ú blue (enzyme b)

       Enzyme A is controlled by a pair of chromosomes AA

       Enzyme B is controlled by a pair of chromosome BB

       Therefore: a_ B_ It’s blue

       A_ BB is yellow

       aaB_ It’s red

       AABB is red

       Of course, color is just a metaphor

       I believe you should be able to understand with your IQ!

       There are more than 25 kinds of cats!! Cats belong to Mammalia, Carnivora, Felidae and feline. Cats are related to lions, leopards and tigers. Cats belong to the same family. Domestic cats are domesticated from wild cats. However, due to different regions and ecological environments, different breeds of domestic cats have been produced. According to statistics, there are more than 100 kinds of cats in the world, of which more than 30 kinds are common. At present, there are four popular classification methods for cats: 1. Western breeds and foreign breeds. Origin classification is a popular method in the West. 2. Purebred cats and cats. It was classified according to the angle of cultivar cultivation. 3. Domestic cats and wild cats. According to the living environment, however, there is no strict boundary between the two. 4. Long haired and short haired. They are classified mainly according to the length of their hair, for example, Persian cat, Himalayan cat, Thai cat and Russian blue cat.

       I found an article that looked very profound.

       The color of the cat

       There are only two colors of cats, red and black. There is no other color. The faded color of red is milky. The fade color of black is blue.

       Color in cats is inherited on the sex chromosome.

       High school biology teacher taught a pair of chromosomes to control the sex of a person. The same is true for cats. The common XY is represented, and the female is represented by XX. Offspring take a letter from their parents. If you take y from your father and X from your mother (you can only take x from your mother), you will get XY, and the offspring will be male. If you get x from dad, the offspring is XX, that is female.

       Because the cat’s color is on the sex chromosome, the cat’s sex chromosome has no color. That is to say, X can be colored. It can be red or black.

       Let’s take an example: a pure red male cat matches a pure black female cat

       The chromosome color of red male cat is x (red) y (colorless) and that of female cat is x (black) x (black)

       … then if their kitten is male (male is XY): it means that the kitten must take a Y from his father, and Y is colorless. So kittens can’t inherit any of the colors of male cats. Because mom is black. So any x the kitten takes on her mother is black. In other words, it must be black. (there may be blue, brown, light brown, and key colors. We’ll discuss these issues later.)

       … if they’re kittens, they’re females (XX): you should know. I will take an X on my father, that is, I will take my father’s red color, my mother will also take an X, and my mother’s black color will also be taken. So the kitten must be two-color.

       For example, if a red male cat x (red) y (colorless) matches a red and black female cat x (red) x (black), then the same calculation can be made that the little male cat can take a color on his mother, X (red) or X (black), that is to say, the little male cat is pure black or pure red. The kitten should take a red on her father and any color on her mother. In other words, the kitten can be red black or pure red.

       Take the red male cat and the red black female cat for example, and make a chart, which should be better understood

       Therefore, the little male cat is impossible to get any color from his father, that is to say, the little male cat can only inherit the color of the female cat. Because the little male cat can only get one color from his mother, the male cat must be monochromatic (explained below for the two-color male cat). Kittens can get at most two colors, red and black, because they inherit one color from their parents. So the two-color cat must be a female cat.

       According to the above rules, you can easily calculate any pure color.

       … but blue and cream are on the solid color list. I personally think that blue and milk color are the result of the desalination gene on the autosomal, and have nothing to do with the color on the cat’s original sex chromosome. CFA’s solid color table is easier to understand if only red and black match the two basic colors. Other colors only weaken the effect of gene and make black and red appear different degrees of desalination. For example, black cats will produce black, dark blue, light blue, and so on. In fact, they are all black, but the density of pigment distribution is different, resulting in different colors in vision.

       CFA’s pure color table actually takes the color genes on the cat’s sex chromosomes and the desalination genes on the autosomal into account. However, there are not only desalination genes on autosomal chromosomes, but also other genes such as whole white, tiger spot, white spot, terminal color, gradients and so on. The function of desalination gene is the same as that of desalination gene, which adds different characteristics to the color inherited by cats.

       For example, the color list says that black male and red male can produce black male and blue male. If blue is one of the possible types, there are also chances to produce chocolate focused kittens and brown male cats. Although such opportunities are rare, there are also fewer opportunities for blue male cats. Only if the black female cat is matched with a milk male cat, it will have a little more chance
