For those of you who have twins, you certainly have a lot of exciting experiences with him. Sometimes, this makes you want to feel the thrill of having twins. However, many people say that it is impossible for twins to have twins too. He said, you have to jump one generation before you can get twin offspring so that there is a possibility that your grandchildren will become twins. Can this be explained scientifically?

Twin genes can only be inherited in cases of non-identical twins

If you have a father or mother who twins, then there is a possibility that you will have twins. The reason is, your body can carry twin genes that are inherited from parents, so it is not impossible if one day you will have twins.

Indeed, there are two types of twins, namely identical twins and non-identical twins (fraternal twins). Well, this genetic factor is more likely to produce non-identical twins than identical twins.

Quoted from Verywell, hyperovulation is one of the causes of women having twins. This case of hyperovulation is also influenced by genetic factors.

Hyperovulation is when a woman releases more than one egg in her menstrual cycle. The two eggs are also fertilized by two different sperm cells, resulting in non-identical twins.

On the other hand, very rare cases of identical twins are caused by genetic factors. Identical twins are considered spontaneous and random occurrences. So, this could happen to couples who do not have twins in their family at all.

Even so, there are actually several types of twins and their uniqueness. What are you curious about? This article is about 7 kinds of twins that you can see.

Have to jump a generation first to get twins?

Being pregnant with twins can occur when the fetus carries the twin genes from its parents, both from the father's side and the mother's side. However, if you have twins now, is there a chance that you will have twins later?

Most people will say no. The reason is, they believe that you have to jump one generation first to get twin offspring. So, if you are now twins as the first generation, then the twin genes will jump over the second generation, namely your children, then the chances are that it will happen to the third generation, namely your grandchildren.

In fact, there is no research that proves that one has to jump a generation first. So, this is a myth. Twins can occur in every generation in the family line.

This myth stems from the wrong assumption about twins. For example like this.

First generation: Grandma

You (woman) have twin grandmothers. This means that your grandmother carried the hyperovulation gene that was passed on to her child. For example, suppose your grandmother has two sons, namely Adam and Rudi.

Second generation: Adam and Rudi

For example, Rudi is your father. Adam and Rudi both carry a hyperovulation gene that was passed down from your grandmother. However, because they are both men, it is impossible for Adam and Rudi to experience hyperovulation.

Third generation: you

You are married, then you are planning a pregnancy. In fact, you get twins, that is, your child and her twin sister who are both girls.

Why does this happen? This is because while you were still in the womb, the hyperovulation gene was passed down from your father. As a result, you experience hyperovulation and allow the occurrence of fraternal twins, aka not identical, as is the case with you and your siblings at this time.

Based on this description, it seems clear that the turnover of twins appears to be skipping a generation. In fact, the reality is not.

This pattern is more influenced by the gender of the hyperovulation gene inheritor, whether male or female. If only your child had twins and produced a daughter, then it could be that her daughter would also have twins because they carry the hyperovulation gene earlier.
