If a sister marries the same man, are the two children born to each other related?

In this case, as you said, the two children are related by blood.

and the two children are brothers.

Relationship. The blood type of the child is the same as that of the father, and the DNA is more than 90% similar to the father, so if the sister gives birth to the same man, the blood relationship of the two children is similar.

Two people who have a common ancestor within a few generations are related by blood, and generally the children of the two sisters are related by blood, and the children of the sisters have only one common father, and the two children are really collateral blood relatives.

If the sisters marry the same man, the two children born separately are of course related by blood, because they are the same father.

Yes, the blood relationship is very strong, first of all, half-father, and secondly, the mother is still a blood relative, and there is basically no difference between the same father and mother.

These two children must be related by blood, they belong to cousins.

Even if they are not sisters, the children born are half-siblings.

There is a blood relationship in itself.

Besides, if it's a sister, I think this relationship should be closer.

Of course, there will be blood relations, after all, they are the same man.

There must be a blood relationship, and all of them are related by blood for less than three generations.

Yes, because the child also had the same man's blood on his body.

Yes, even if you don't marry the same person, you are related by blood.

But why did the sisters marry the same man?

Half-sibling, or cousin, must be related by blood.

This is a natural blood relationship, and it is a very close blood relationship.

Isn't this nonsense? There must be a blood relationship, a boy's child.

The two children of the pig must be related by blood, because they are the same father.

Yes, because they are the same father.

This is a high degree of blood inbreeding, with DNA similarity above 98%.

In ancient times, men could have three wives and four concubines, so it often happened in history for men to marry sisters, and ancient women had long been accustomed to it, but at that time, it was not ordinary people who could marry sisters, they were generally high-status people, either princes and nobles, or emperors, especially the emperor, he was the honor of the ninety-five and the whole world was his, and ancient women had no status at all, and they could not control their own destiny at all, and could only obey their parents. And how many people want to attach to the royal family, parents are also trying their best to send their daughters to the palace.

Because in ancient times, women were originally vassals of men and had no status at all, so it was normal for two sisters to marry a man.

Because at that time, there would be no consciousness that close relatives could not get married, and they would not care about this kind of thing, just look at the face.

It is possible that the odds are 1 in 16.

The reason for this is that each person's chromosomes come from their father and their mothers respectively. Twins are no exception, and there are 4 genetic possibilities for twins and twins born to children. Two of them are male and two are female.

With the permutation, c41 c41 = 16So the possible outcome is 1 16.

The probability of the same is almost non-existent. Because the appearance is determined by various aspects, by the genes and the environment, and the blood type between the twins may not be the same.

Based on genetics, I personally think it's very likely that the children born to the two couples look exactly the same.

No, the slightest difference will cause a difference in the appearance of the child, which is like a branch, which will get bigger and bigger.

Because women in ancient times were generally political victims. The status was not high, and it was normal for sisters to marry the same person at that time.

Because in ancient times, the status of women was relatively low, and it was very normal for men to have three wives and four concubines, and sisters marrying the same man could take care of each other without too many constraints.

Because the status of women in ancient times was very low, and they only became vassals of men, it was normal for sisters to marry the same person.

Because in ancient times, those princes and nobles were polygamous, and many of them were two sisters married to one husband, and it was not unusual for two sisters to marry one husband in their time.

The easiest place for this kind of thing to happen is the royal family, why marry the same man, because you want to be protected by that man, and in ancient times it was polygamous, it is not a problem.

Historically, when a sister marries the same man, I personally think there are two possibilities: 1. Forced by the situation, the family needs; 2. It may be true love, and the other party agrees.

Because in ancient times, it was a patriarchal era, and women could only resign themselves to fate and listen to their parents and husbands, so there would be cases where sisters married a person.

Because in ancient times, women were vassals of men, and their social status was very low, so this situation occurred.

In ancient times, women had a very low status, and they were vassals of men, so it is not surprising that two sisters marry the same man.

In ancient times, many men were forced to serve in the army, resulting in death, so that the wives and children at home would be miserable, and if the sisters were together, they could take care of them.

Because the phenomenon of three wives and four concubines of men in history is very common and very normal, sisters marrying the same man can reduce conflicts and live peacefully.

Tang Yao married his two daughters to the same man, Empress E and Nu Ying served a husband, in line with the interests of Tang Yao's family, although Yu Shun and Tang Yao are both descendants of the Yellow Emperor, but after all, the blood relationship is far away, and the relationship is estranged, marry the daughter to Yu Shun, Yu Shun is the son-in-law, a son-in-law is half a son, but if the son-in-law and the daughter have no offspring, no son, the identity of the son-in-law is not reliable, in order to ensure that the son-in-law will be able to have offspring with the daughter, marry the two daughters or even three daughters to the same man, It is very necessary. If you don't have so many daughters, marry your daughter's nieces together. This way of marrying is called "wife", "wife" is a kind of wife, but there is no status of the wife, although there is no status of the wife, but the children born have the status of sons-in-law and daughters-in-law, and have the same inheritance rights as the sons of the main wife.
