How much does family inheritance affect a person's health?
Hereditary diseases are diseases caused by changes in genetic material. Hereditary diseases are congenital, familial, lifelong and hereditary. A single gene often shows functional changes, can't produce protein, has metabolic dysfunction, and forms metabolic genetic diseases. Dominant inheritance: if one parent has a dominant gene, once it is passed on to the next generation, it can get sick, that is, if there is a sick generation, there must be sick offspring, and it will be passed down from generation to generation, such as polydactyly, syndactyly and primary glaucoma. Recessive inheritance: such as congenital deafness, high myopia, albinism, etc. It is called recessive genetic disease because the parents of children are often normal in appearance, but they are all carriers of pathogenic genes. Sex-linked inheritance, also known as sex-linked inheritance, is related to gender, such as hemophilia, whose mother is the carrier of pathogenic genes. Another example is red-green color blindness, which is cross-inheritance. The son comes from the mother and is the carrier of the pathogenic gene, and the daughter comes from the father, but the incidence rate of men is much higher than that of women. Polygenic inheritance: it is caused by the influence of various gene changes, and it is the relationship between genes and traits. People's body length, body shape, intelligence, skin color, blood pressure and other traits are polygenic inheritance, as are cleft lip and palate. In addition, polygenic inheritance is greatly influenced by environmental factors, such as asthma and schizophrenia. Chromosome abnormality: due to abnormal chromosome number or arrangement position; The most common type is congenital stupidity. Such children have dull face, mental retardation, wide eye distance, strabismus, tongue coating dementia, hand penetration, and often complicated with congenital heart disease. As the basic environment for children's growth, family directly or indirectly affects children's physical and mental growth and development through feeding, education and behavior training. The degree of attention, care, care and financial support of other members will affect the physical recovery, aggravation and even death of sick family members.
