It is a legal requirement that close relatives cannot marry, which can cause extremely serious harm to the health of the offspring and the family. The next generation is more likely to suffer from albinism, congenital malformations, genetic diseases, and IQ is also likely to be affected. At the same time, it is not good for the family, if the next generation really has health problems, it is easy to fall into the mouth, and the family also needs to bear high medical costs for the child's treatment, affecting the feelings of husband and wife.
Close relatives (or relatives) are those who share a common blood relationship among three or less generations. In the marriage of close relatives, because the two parties have too many similar genetic factors, the offspring cannot produce mutations from them, and the harmful genes will be passed on to the offspring.
First, harm to future generations
Consanguineous marriage will have extremely serious harm to the next generation, mainly divided into the following aspects:
1, offspring born to close relatives are more likely to develop albinism, because two people are more closely related to each other, which will increase the chance of disease. According to the survey, the risk of albinism is 13.5 times higher when married to close relatives, which is extremely unfavorable to the development of offspring.
2, in addition, the IQ of children born out of consanguineous marriage will also be affected, and their offspring are generally low in IQ, and are also very prone to congenital abnormalities.
3, the child born to the marriage of close relatives is also more likely to suffer from congenital malformation, is likely to die early or incomplete development, so for the future of the next generation, it is recommended that we do not take this risk, try not to marry close relatives.
4, in addition to the above diseases, another great harm of close relatives is that it may lead to offspring suffering from polygenic genetic diseases, which mainly include hypertension, schizophrenia, and even life-threatening in severe cases.
Second, the harm to the family
1, the marriage of close relatives will inevitably fall into the mouth, a day or two is fine, for a long time, it will inevitably have an impact on the feelings of the husband and wife, so that the husband and wife have great pressure, thus aggravating the contradiction, and eventually lead to divorce.
2, in addition, if the child suffers from diseases because of the marriage of close relatives, the family needs to bear high medical costs for treatment, and these pressures will aggravate the contradiction between husband and wife, resulting in the phenomenon of quarrels between the two sides.
Therefore, whether for the sake of future generations or for the sake of the family, it is recommended that people do not marry close relatives.
