What's the experience of being one of the twins? In fact, I personally think that the experience of being one of twins is of course good, because the probability is really small, and if the child is in the mother's body. Everyone has a different personality. One child can have two children, which is what parents want to see most, and they suffer less. Of course, parents will be particularly happy if their children are born healthy. Even with high hopes. This kind of efficiency will always be envied.

Anyone who has studied biological knowledge knows that there are two kinds of twins, namely identical twins and fraternal twins. Identical twins are fertilized eggs, which divide into two cells under certain conditions, that is, there are two eggs in the body, but they are exactly the same. After such cells grow and develop, twins are identical twins, with the same sex, blood type and appearance. Fraternal twins are two children born of two fertilized eggs with different sperm and eggs. They are essentially the same as ordinary brothers and sisters, only one pregnancy and one birth, which is a special situation. The first necessary condition for twins is fraternal twins. This requires two fertilized eggs. Because the combined sperm is different from the egg, and the X and Y chromosomes on it are also different, it is possible that one sex is male and the other sex is female. Of course, not all fraternal twins are twins. We often see two identical twins with different looks, which are also fraternal twins. If one of the two fertilized eggs conceived in the body happens to carry the X chromosome and the other carries the Y chromosome, only in this case can twins be conceived. However, the probability of twins is small, which is consistent with fraternal eggs and different X and Y chromosomes, which is also the reason for the small probability of twins. But now not only twins are increasing, but twins are also increasing.
