Because female cats can reproduce more effectively, thereby increasing the population. In addition, the three-cat cat has stronger masculinity and can better protect itself and its family, so it is more likely to be popular among people.
Among the many cats of color, the three-cat cats are the most special because they have three fur colors. What's more special is that most of the three-cat cats are female cats, and the three-cat cats are rare. The color blocks of different colors are actually the external manifestations of the cat's DNA and are determined by the X chromosome. For female cats, the chromosome is XX, one of which is the color of orange and the other which is the color of black.
And a male cat has only one X chromosome, so it can only display one color. In fact, all three-bean cats have Kerry's syndrome, which means they have two X chromosomes. Because of the 23rd pair of chromosome abnormalities, they have one more X chromosome than normal male cats, so their gene map is XXY.
The chance of this genetic defect happening in humans is only 0.2%, while the chance of happening in cats is even smaller. So if you have a three-frank cat in your house, it is really rare.
It is precisely because of this genetic defect that the three-gama cats are basically infertile. Don’t discriminate against the Three Flower Cat just because it cannot give birth. You should know that the prototype of the Three Flower Cat is the Three Flower Cat. So in a sense, the three-gama cat is also a symbol of good luck. If you are lucky enough to meet such a cat, please cherish it.
