Abstract: when it comes to heredity, many people unilaterally believe that since it is a genetic disease, the parents of myopic patients must also be myopic, and the children of myopic patients must also be myopic., According to the current research, it is certain that myopia is a genetic disease. Therefore, genetic factors are a major cause of myopia. Whether simple myopia or pathological myopia, they are a genetic disease, but the genetic law is not exactly the same., When it comes to heredity, many people unilaterally believe that since it is a genetic disease, the parents of myopia patients must also be myopia, and the children of myopia patients must also be myopia. It seems too simple to look at the problem this way. Genetic disease refers to a disease that is passed from generation to generation through a certain pathogenic gene and according to a certain law. So what is the genetic law of myopia?, Pathological myopia is passed on to offspring according to the rule of autosomal recessive inheritance. The difference between red and green color blindness is that it has nothing to do with gender. Only locally, if one of the parents is suffering from rational myopia and the other is a homozygous normal person, the children born are myopia gene carriers (hereinafter referred to as carriers); If both parents have pathological myopia, their children will be patients with pathological myopia; One of the parents has myopia and the other is a carrier. Half of the children born may be patients and half may be carriers; If both parents are carriers, 1 / 4 of their children may be normal, 1 / 4 may be patients, and 1 / 2 may be carriers., Of course, the problem is not so simple, because it is impossible to accurately judge the carrier. Some people think that patients with simple myopia are carriers. Some people disagree with this view and think that these are two different myopia diseases. In addition, early pathological myopia is difficult to distinguish from simple myopia, which increases the complexity of analysis.,

when it comes to heredity, many people unilaterally believe that since it is a genetic disease, the parents of myopic patients must also be myopic, and the children of myopic patients must also be myopic. It seems too simple to look at the problem this way. Genetic disease refers to a disease that is passed from generation to generation through a certain pathogenic gene and according to a certain law. So what rule does myopia inherit?
pathological myopia is passed on to offspring according to the rule of autosomal recessive inheritance. The difference between red and green color blindness is that it has nothing to do with gender. Only locally, if one of the parents is suffering from rational myopia and the other is a homozygous normal person, the children born are myopia gene carriers (hereinafter referred to as carriers); If both parents have pathological myopia, their children will be patients with pathological myopia; One of the parents has myopia and the other is a carrier. Half of the children born may be patients and half may be carriers; If both parents are carriers, 1 / 4 of their children may be normal, 1 / 4 may be patients and 1 / 2 may be carriers.
of course, the problem is not so simple because it is impossible to accurately judge the carrier. Some people think that patients with simple myopia are carriers. Some people disagree with this view and think that these are two different myopia diseases. In addition, early pathological myopia is difficult to distinguish from simple myopia, which increases the complexity of analysis.
