What kind of cat does Sanhua give birth to – why are they all female?

       You think it’s up to you to decide not to produce tricolor… Your mother cat is a three flower cat. Unless you don’t keep it or you don’t let it give birth, it has a chance to give birth to three flowers… What’s wrong with you… There is no saying that it looks good or not.. Every cat is very cute, all are elves, if you really love cats… No matter what kind of cat is a lovely incarnation… No matter what color cat you match, because the female cat is a tabby cat, most of the cats destined to be born are flower cats… There are few solid colors… No matter what color you match, it’s the same, because my family has two flowers and three flowers… I understand. Even if it is matched with pure white, the same kind of cat will be born, and the tiger spot will give birth to a half tiger spot and a half white one. Most of the cat with yellow and white color will be yellow and white…. You can try.. No matter what match, it is possible to produce three flowers.. Unless you don’t let it live~~~~

       This is related to the chromosomes inherited by coat color.

       First of all, there are only two kinds of fur on the cat, yellow (called red by foreigners) and black. White is not a kind of fur color. Cat’s hair appears white only because its color is not revealed for some reason. The gene controlling coat color exists on cat XY chromosome, which is a pair of sex determining chromosomes. Therefore, the inheritance of coat color in cats is also called sex linked inheritance.

       Second, the genes that determine coat color only exist on the X chromosome. An X chromosome can only carry one color information. Y chromosome has no effect on coat color. In genetics, Y chromosome only exists in male, that is, XX combination, sex is female, and XY combination is male.

       Get x from the mother. ¢Ù if you get x from your father, it’s a female cat (XX), which can carry one or two colors of information; ¢Ú if you get Y chromosome from your father, it’s a male cat (XY), which can only carry one color information.

       So, if you see a cat with two colors of black and yellow, it must be a female cat. With white, it is three colors.

       Although there are few male sanhuamao cats in the world, they are definitely not without one. Cats will pass on their own physical and personality characteristics to their children, and Sanhua cat is more special. It can’t inherit the characteristics of Sanhua and male at the same time. The three flower male cat’s birth rate is only 0.1%, but these male cats wearing tricolor coat have little ability to breed the next generation.

       Ali, a little red fox in white underwear. In 2006, the author, Hans, published the story of Ali on the Internet. The forum post with its leading role quickly exploded tens of millions of hits, and has been accompanying you with a warm and healing image.

       Who is Xiaoyu stationmaster? Originally, it was a common black orange white three spotted cat, who lived in the grocery store at Guizhi station of guizhichuan tram line in jizhichuan City, Keshan County. In 2007, guizhichuan line was abandoned due to poor operation, but Xiaoyu successfully saved the tram line. It was not only appointed as the stationmaster of Guizhi station, but also created cartoon images for him.

       Xiaoyu is on duty like a civil servant, attracting millions of tourists to come to see her every year. In 2015, the first Xiaoyu stationmaster passed away, Guizhi station looked for a new cat stationmaster to continue this culture.

       Ali and Xiaoyu, the two warm hearted cartoon images, will jointly create a more healing story? The 2018 China cartoon image marketing conference specially invites Ali to tell you about his communication with Xiaoyu.

       As a domestic original animation image, Ali has more than 20 million online fans, more than 3 million picture book sales, more than 1 billion animation plays, more than 5 billion QQ emoticons, more than 300 million wechat emoticons and more than 100 authorized partners.

       With the approval of the Ministry of culture and tourism (formerly, *), the 2018 China cartoon image marketing conference will be held at Hilton Yilin Hotel, Guangzhou Development Zone from April 10 to 11, jointly sponsored by China Animation group and China Advertising Association, hosted by Huangpu culture group, supported by the news center of * * and the Department of culture of Guangdong Province, and co organized by Guangzhou animation industry association. This is the only innovative animation exhibition with the theme of the integration of animation and real economy in China, which is expected to attract 800 enterprises to participate.

       April 10 in Yangcheng, Arie will meet you at the 2018 China cartoon image marketing conference!

       Because the cat’s coat color inheritance is sex linked, only a female cat with two X chromosomes may have three colors.

       We know that genes can greatly affect the phenotype of organisms. Coat color genes only exist on the X chromosome. An X chromosome can only carry one color information, while Y chromosome has no effect on hair color.

       There are only two colors determined by the X chromosome: orange and black. White is not a kind of hair color. Cat’s hair appears white only because its color is not revealed for some reasons.

       Female cats have XX chromosomes, so they may have orange, black and white colors, while male cats have XY chromosomes with only one X chromosome, so there may be at most two colors. Therefore, three flower cats are female cats.

       Extended data

       In the case of genetic abnormalities, male cats may still show tricolor, but most of these cats have reproductive problems because of their three chromosomes.

       Mammalian female XX two chromosomes, that is, any gene has a pair, more than a male. In order to maintain the normal expression level, one of these genes is turned off during development, that is to say, each individual cell expresses only one gene on two X chromosomes randomly. That is to say, female somatic cells may express genes randomly from their father or mother’s X chromosome. It is because of the genes on the X chromosome with two different colors that express one or another randomly in the hair of female hawksbill cats, and the expression level may be different, so the tortoiseshell fur will appear.

       Female cats have two XX chromosomes, that is, each gene has a pair, one more than male. In order to maintain the normal expression level, one of the two genes is turned off during development, that is, each individual cell expresses only one gene on two X chromosomes randomly.

       In other words, female cells may express genes from their father or mother’s X chromosome.

       And the genes that control tricolor are associated with genes that control sex. We call them sex linked genes, because the genes that determine black and orange are sex linked and are located on the X chromosome.

       If the cat’s genes are randomly inactivated during differentiation, the black gene in the hair color cells may be inactivated and show orange color, otherwise, it will be black. Therefore, most of the three genes are female.

       Extended data:

       Although there are few male sanhuamao cats in the world, they are definitely not without one. Cats will pass on their own physical and personality characteristics to their children, and Sanhua cat is more special. It can’t inherit the characteristics of Sanhua and male at the same time.

       In other words, female somatic cell expression may randomly express genes from the father or mother’s X chromosome. The female hawksbill cat has two genes on the X chromosome with different colors, which randomly express one or another in her hair, and the expression level may be different, so it shows the tortoiseshell fur.

       Different color blocks are actually the external manifestation of cat DNA, which is determined by X chromosome. For a female cat, the chromosome is XX. One of the X is orange and the other is black.

       Male cats have only one X chromosome, so they can only show one color. In fact, all three male cats have Creutzfeldt’s syndrome, which means they have two X chromosomes. Because the 23rd chromosome is abnormal, they have one more X chromosome than normal male cats, so their gene map is XXY.

       This genetic defect is only 0.2% more likely to occur in humans than in cats. So if you have a male cat with three flowers in your family, it is quite rare.

       Extended data

       The gene that determines the color of cat’s fur only exists on the X chromosome, while the color gene often shows quantitative inheritance. Different additive effects often show the Yellow Black phenotype. When a cat displays three colors, it indicates that there are black gene and yellow gene in the body. The result of the cooperation of the two genes is that part of the coat color appears white, and it becomes a three flower cat. Because the sex chromosome genotype is XX, it is all female.

       It happens that my cat is such a match, generally will rate out yellow white cat, of course, tiger spot three flowers can also have, for example, my family, gave birth to four, only one is three flowers, the others are yellow and white, in fact, three flowers with black and white match is more beautiful, my other is also three flowers with black and white, born out are very beautiful..
