If one of the husband and wife has three genetic diseases, it is better to be a daughter!
One: red and green color blindness
If there are many people who are red and green blind in our present life, it will easily bring a lot of trouble to our life and work, and many careers may not be considered. If they join the army or the pilots are color blind, they will definitely not be able to participate. If one of their parents is red and green color blind, then if the baby born is a boy, the chance of getting sick is about twice as high as that of a girl, and most of them are red and green color blind in life.
Two: hemophilia
Genetic diseases and color blindness are actually the same. If the mother has a new shoelace, it probably won't happen to her daughter, but if a baby boy is born, hemophilia is likely to occur. It is impossible for everyone to know about hemophilia. In fact, hemophilia is a terrible genetic disease, which usually occurs around the age of five. It is very dangerous for children. If children bump into each other or get sick, they will often suffer from massive bleeding, spontaneous bleeding, blood coagulation and so on. If the mother has this gene, then it is best to pray for the health of the child.
Third, silkworm bean disease
It's strange for everyone to talk about silkworm bean disease, and they may not even have heard of it. In fact, silkworm bean disease is also a very common hereditary enzyme deficiency. Once a person gets the disease, the stability of red blood cells in the human body will get worse and worse, which is easy to cause injury and hemolytic anemia. Children will get sick when they are about nine years old, and their skin will get darker and darker when they get silkworm disease. Even when the urine has a serious soy sauce color, anemia will occur. If the silkworm bean disease is not well controlled, it is likely that the child's liver and kidney problems will be affected to some extent, which will slowly lead to failure, which is very dangerous for the child. In fact, there is a preference for boys over girls, so parents with this disease had better pray for a baby girl.
