How is twins transmitted?

The question of how twins are inherited are of interest to many women. After all, giving birth to two children and forever forget about the suffering and suffering that a woman experiences during childbirth, many girls want. Let's take a closer look at this issue, and tell you about the probability of the birth of twins and whether it is inherited.

How is the possibility of twins borne?

Currently, there are several theories that explain the possibility of the appearance in the family of two babies at once. The hereditary theory was most widely spread. So, according to her, the ability to give birth to 2 children is transmitted exclusively through the female line. This is explained by the fact that for the conception of twins, it is necessary that a phenomenon occurs in the body of a woman, such as hyperovulation. In this case, for 1 menstrual cycle in the body, two eggs mature simultaneously, which subsequently leave the follicle into the abdominal cavity, and are ready for fertilization with spermatozoa.

According to this theory, if the future mother herself has a twin or sister, the probability that she will give birth to two children at once increases by about 2.5 times, compared to other pregnant women. Moreover, if the mother already has twins, the probability that as a result of the second pregnancy there will be two more children, increases by 3-4 times.

It should be noted that men can also be carriers of the hyperovulation gene, which he can pass on to his daughter, i.e. if the spouse in the family had twins, then it is likely that he can become a grandfather at the same time 2 babies.

How are twins transmitted in the family?

Having told about the possibility of the birth of twins from parents to children, let's follow this pattern on the example of 3 generations of twins.

So, for example, in the 1st generation, the grandmother has a hyperovulation gene, and she has twin sons. In view of the fact that men can carry the hyperovulation gene, they do not have this process in the body, so the probability of having twins is low. However, if they have daughters, then those, in turn, can give birth to twins, because there is a high probability that the gene of hyperovulation will be inherited from the fathers.

Thus, it can be said that in order to give birth to 2 children at once, it is necessary to have a twin in the genus of a woman. At the same time, the closer the generation, in which there was twins, the probability of becoming the mother of two children is higher.
