In ancient times, it was popular for cousins to marry cousins, but why did they rarely give birth to deformed children? The reason is very simple
At present, the laws of the country stipulate that marriage between close relatives is not allowed, because the probability of children born from close relatives marriage is very high, and such provisions of the law are also for the consideration of the people.
But in ancient times, many of them were close relatives who married, and some large families would let their cousins get married in time in order to be able to kiss each other, but why did few children hear about deformities in ancient times?
In ancient times, people's marriages could not be mastered by themselves, and they all obeyed the orders of their parents and the words of matchmakers.
Moreover, in ancient times, people did not know the seriousness of genetic problems, so it was normal for all kinds of cousins to get married.
Not all children born of consanguineous marriage will have problems, some may look the same as normal people, but there will be big problems in the recessive genes.
And many more deformed children will not be born at all.
After research, if a close relative is pregnant with a child after marriage, the child's development in the womb may not be particularly smooth, and most of the deformed children will have miscarriage.
In ancient times, although there was such a thing as fetal protection, because of the child's development problems, most of the deformed children were miscarried in the womb.
And some people will die of illness not long after birth, there are many such things in ancient times, the ancients did not realize that this is the consequence of the marriage of close relatives, only think that it is more difficult to raise children.
Moreover, in ancient times, men were inferior to women, and the status of women was relatively low, and men could take concubines after marriage, and there could be no close relationship between ordinary concubines and men, and the main wife of the family would have this relationship.
If you get close to the marriage, the wife will be carefully raised after pregnancy, but many of them still have miscarriages during pregnancy, which may be because of the deformity of the child in the womb.
If the child can be born normally, then there is a high probability that the child will be a normal child.
There is a Chinese idiom called "Jinwu Zangjiao", which refers to the marriage of close relatives.
Emperor Wu of the Han Dynasty, Liu Che, fell in love with his beautiful cousin Chen Ajiao at a young age, Chen Ajiao was his aunt's daughter, that is, Liu Che's cousin.
Later, after he became Emperor Wu of the Han Dynasty, he was even more anxious about Chen Ajiao, and threatened to build a golden house and hide Chen Ajiao.
But two people are close relatives and married, and there is a blood relationship.
In ancient times, it was very normal for people in the family to get married, and later after the founding of New China, it was announced that close relatives could not get married.
Close relatives refer to immediate relatives who are related by blood, and collateral relatives within three generations, so there is no longer a situation of close marriage in the country.
But why did the ancients let the children of their family marry and not choose anyone else?
Ancient people did this because people looked at the glory of the family very much, some ancients became officials, they would help their relatives, after the recommendation, the family members were in the court.
And in order to ensure that the glory of his family will not be shaken, he will let the children of the two families become husband and wife, so that the status will be more solid after kissing and kissing.
And the two families will be more helpful and take care of the children, and the relationship between the two families will become better.
Another part of the reason is that because of the right family, in ancient times, it was impossible for poor peasants to marry a wealthy and noble lady, and then when choosing a future marriage partner for their children, appearance, family background, and knowledge were very important.
But there are not many people who are right, so it is not so easy to choose, and in the end, I still feel that my relatives are more suitable, which also leads to more marriages between close relatives.
But because they didn't know about genetic problems, the ancients didn't know that there would be recessive diseases and malformed fetuses when married between cousins and cousins.
But during the Zhou dynasty, a law was enacted to improve the marriage of close relatives among the Chinese.
During the Zhou Dynasty, there were many family marriages, and many people did not allow their children to marry out, and some were even unwilling to face the royal marriage.
The power between the families is becoming more and more serious, and some families are too large to even threaten the power of the royal family.
In order to prevent such a thing from happening, the Zhou dynasty ordered that all people with the same surname could not marry, and after the promulgation of this law, the phenomenon of close relatives marrying was greatly reduced.
This also had an impact on the development of later dynasties.
It was not until after the founding of the People's Republic of China that the state promulgated clear regulations.
And with the progress of the times, people's awareness of genetic problems has also become very understanding, knowing that consanguineous marriage can bring terrible consequences to people's lives.
Modern people obey this law, and people's lives have become different from those of the past, and the law also stipulates monogamy, which is no longer the same as it was in the past.
