Statistics show that the incidence rates of polygenic genetic diseases or congenital malformations such as hypertension, schizophrenia, congenital heart disease, anencephaly, spina bifida, and epilepsy are significantly higher in children born from consanguineous marriages than from non-consanguineous marriages.

Article 7 of the "Marriage Law of the People's Republic of China" clearly stipulates that marriage is prohibited between people who are close relatives, such as direct blood relatives and collateral blood relatives within three generations.

Reasons why children of close relatives are susceptible to genetic diseases:

Many genes between close relatives come from a common ancestor, so they are more likely to carry the same disease-causing genes. In this way, the prevalence of genetic diseases in children born from marriages is much higher than the prevalence of genetic diseases in children born from non-consanguineous marriages.
