Tortoiseshell cat, when you hear this name, many people will be confused. Everyone will think, what kind of cat is this? In fact, the name of tortoiseshell cat is not a breed, but a general term for cats of a certain color. So is this cat valuable? Let me tell you below.
The price of tortoiseshell cats is not very high and is not very valuable. Generally speaking, the price of tortoiseshell cats is around 3,000 yuan, which is related to the quality. The tortoiseshell cat (tortoiseshell cat) comes from a type of sea turtle - tortoiseshell. Because its fur color is very similar to that of sea turtle tortoiseshell cat, it is called a tortoiseshell cat.
Tortoiseshell cats generally have uniform fur colors and visually look fluffy and softer than monochrome cats. A tortoiseshell cat with better fur color is like under a tree in the afternoon of autumn. The sun shines through the mottled shadows of yellow leaves on the ground and disappears into the grass. It is really a very good protective color. If there is such a tortoiseshell cat at home, the owner will love such a special little thing very much because it is difficult to get confused with other people's cats. What’s even more interesting is that many tortoiseshell cats have obvious black and yellow fur on their faces, which looks like they have a big flowery face, which is very cute.
All cats with yellow and black hair colors are females, because the yellow hair gene (b) is an X-linked recessive gene, the black hair gene (B) is its dominant allele, and the female homozygous hair color is yellow (bb) or black (BB).
The female hybrid (Bb) will be randomly inactivated in the early stage of embryonic development, that is, one X chromosome is highly curled (Paptite) and loses physiological activity, resulting in only one X chromosome in the cell. If the X chromosome containing b is inactive, B appears black, and if the chromosome containing B is inactive, b appears yellow. Since the X chromosome in cells in different parts of the cat's fur is random, the color of the cat's hair is mottled and randomly distributed, becoming a tortoiseshell color that is yellow and black.
Occasionally male tortoiseshell cats are because their sexual chromosome composition is XXY, not normal XY. You can look at the cats around you. As long as there are more than three types of fur on your body, most of them are female cats, but the tabby pattern can only be considered one. Generally speaking, the probability of tortoiseshell white cats and tortoiseshell cats giving birth to tortoiseshell cats is much greater than that of other color cats. Due to genetic reasons, the fur color of cats in modern times will hardly change much, so it is impossible for pure white cats and pure black cats tortoiseshell cats tortoiseshell cats tortoiseshell cats.
