On the evening of October 10, Myolie Wu 's husband shared a picture of celebrating his eldest son Li Yiting's fifth birthday on social platforms. In the photo, Brendan is wearing a yellow T-shirt, a yellow birthday hat, a stick in his hand, and a cute smile. Myolie Wu's family sat neatly on the sofa and took a group photo. The eldest was sitting in front of the cake, Myolie Hu was holding the second child, and her husband Li Chengde was holding the third. The two younger brothers also wore yellow T-shirts with their elder brothers, and they were full of cuteness.
Is it true that female stars called "children" are more likely to have sons? You see, on October 13, 2017, Myolie Wu gave birth to her eldest son, Li Yiting; on July 6, 2019, her second son, Li Yilin, was born. On April 6, 2021, Myolie Wu's third child Li Yihong (Liam) was born, and Ying Caier has two sons, Le Jier gave birth successfully in 19 years... Just, inexplicable feeling of "believing in your evil" .
But everyone knows that having a boy or a girl depends on the father, and it has nothing to do with the mother as a legal person, and secretly tell everyone that the potential "risk" of having a boy is even greater! Why do you say that? I have to mention a saying - "Let's pass on a man but not a woman". Generally speaking, everyone will think of those bloody heirloom plots. In order to ensure the purity of the family blood, any martial arts secrets and family secrets are passed down to men and not to men. Pass the female. However, if you think that all babies are passed on from males to females, then you are wrong, because some genetic diseases are only passed on to males and not females.
Then there will definitely be sisters to ask, why only males and not females? To put it simply, because there are 23 pairs of chromosomes in our human cells, 1 pair (2) is the sex chromosome that determines sex, XX for females and XY for males. If a gene mutates, a disease can occur and can be passed on to future generations. Sex-linked inheritance occurs when the disease-causing gene is on the sex chromosome.
Simply put, for a woman, a woman must have a disease-causing gene on both X chromosomes ; if only one X chromosome has a disease-causing gene, then she is only a carrier and will not be diseased. For males, he has only one X chromosome, so as long as this X chromosome carries the disease-causing gene, he will be sick.
So, what are some common male-non-female genetic diseases?
【Red-green colorblind】
When it comes to red-green color blindness, many people will immediately think: It's troublesome to cross the traffic lights! Red-green color blindness is a congenital disorder of color vision, which is difficult to distinguish between red and green.
Maybe you will find that most of the colorblind are male. Saying that color blindness is a hereditary disease of "passing on from male to female" does not mean that all color blindness is male, but that males are more likely to be color blind.
Daughter may be colorblind only if both parents are colorblind, or if the father is colorblind, and the mother has colorblind genes; for boys: as long as the mother is colorblind, the son must be colorblind; if the mother carries the colorblind gene, the father is normal, and the son is also colorblind. Most likely color blind.
【Baldness】
Many male compatriots have encountered the problem of baldness. Although it is not a serious problem to the body, it still has a slight impact on the image... Not all baldness is inherited, don't blame the elders for anything It may also be caused by your own mental stress, irregular life, diet or other diseases.
In general, the creator seems to be more biased towards women, with a much greater chance of male baldness. For example, if the father is bald, there is a 50% chance that it will be passed on to his son. Even the mother's father will leave the 25% probability of being bald to his grandchildren.
【hemophilia】
The blood of patients with hemophilia lacks an important coagulation factor, antihemophilic globulin, which causes coagulation dysfunction spontaneously or after mild trauma, and the bleeding cannot be stopped after , the risk is relatively high.
And hemophilia is also passed on from male to female, which means that if the father has hemophilia, or the mother has a recessive gene for hemophilia, then if a son is born, the chance of hemophilia will be higher. It's very big, but it's generally not a problem if you have a daughter.
In addition to this, there are also broad bean disease and pseudohypertrophic progressive muscular dystrophy, which are also diseases that are passed on from males to females. Now everyone pays attention to prenatal and postnatal care, so before we prepare for pregnancy, we must do pre-pregnancy Check, and both husband and wife should take the initiative to confess to the doctor whether there is a history of genetic disease in their family, so that the doctor can help you to avoid some targeted ones~
