Why are twins born on different days?

Twins are born on different days, which is medically known as multiple delayed delivery. This measure is to ensure the safety of the mother and the fetus, generally twins are born early, prolonging the gestation time of the fetus in the mother's body, in order to improve the maturity of the fetus, has great benefits to the health of the mother and the fetus.

Summary. Hello, the birthday is the same day, but not twins, this situation is rare, but there are related cases, because there are twins belonging to two independent fertilized eggs in the mother's belly, and then the due date is different, one belongs to the early caesarean section, so it is possible that there is such a situation, this situation is biological. If it is not the above situation, then it may be an adopted child, deliberately hidden by the family, I hope it can help you!

The birthday is the same day, but it's not a twin, it's biological.

Hello, it may be biological, your question has been shortened, and the answer is being sorted out for you in more detail, please wait two minutes.

Good. Hello Hail He Xian, the birthday is the same day, but not twins, this situation is rare, but there are related cases, because there are twins belonging to two independent fertilized eggs in the mother's belly, and then the due date is different, one belongs to the early caesarean section, so it is possible that there is such a situation, this situation is biological. If it is not the above situation, then it may be an adopted child, deliberately hidden by the family, and I hope to help you!

It doesn't look like it. Hello, the above is not like the possibility of not looking like, because two independent fertilized eggs are two banquet judgment change individuals, not belonging to a fertilized egg differentiation of twin cases, so it will not look like it, if it is indeed born of pro-to-wax, then the two children are not like, then it is the first case, I hope to help you!

Birthdays on the same day, but not twins, are they biological?

Generally, twins are born in order, and the time when the two babies are born will not differ too much, usually just a few minutes.

Twins are usually born one after the other. Usually don't come out together. The more capable ones come out first. The weaker ones come out later.

Twins can be said to be born in line, one is born first, and then the other, which is equivalent to having two children in a row.

More twins are being born than ever beforeBecause of assisted reproductive technologyIt began to rise in the 70s of the last centuryPushing for an increase in the number of twins, coupled with older maternal age, the chance of conceiving twins is also higher

According to Agence France-Presse on March 12, a study published in Human Reproduction found that more than 1.6 million pairs of twins are currently born each year.

According to the report, researchers collected data from 135 countries from 2010 to 2015. According to the study, Africa has the highest twin birth rate in the world because of the "genetic differences" between Africa and the rest of the world.

In addition, the researchers say the increase in twin births in poorer parts of the world is worrying. Smith, co-author of the study, said: "More attention needs to be paid to the ...... fate of twins in low- and middle-income countriesEspecially in sub-Saharan Africa, many twins lose siblings a year after birth.

There are two cases of twins, one is dizygotic twins, and the other is monozygotic twins, and if they are dizygotic twins, they will look different.

My cousin is a pair of twins, the two of them look a little bit, not the slightest bit different, although they are a father and a mother, but they are not the same egg, right? So it's impossible to say that two twins will look exactly the same.

Twins are the conditions in which a viviparous animal conceives two individuals at a time. Twins can generally be divided into two categories: identical twins and fraternal twins. Identical twins are two fetuses that develop from a single fertilized egg, and fraternal twins that develop from different zygotes.

Normally, a woman ovulates 1 time a month, and sometimes for some reason two egg cells are released at the same time and fertilized at the same time, resulting in two different fertilized eggs. The two fertilized eggs each have their own set of placentas and have no connection with each other, called fraternal twins, and the mother will give birth to two babies. They are more similar and tend to be of the opposite sex.

This type of fraternal twin is more common and is related to genetics, the age of the pregnant woman, and the number of births of the pregnant woman.

33) The twins are too different in appearance, and the whole family suspects that they have done a paternity test, and the result is embarrassing for Bao's father.

I think it may be due to a heavy pregnancy, because in this case, one fetus is delivered at term and another fetus continues to develop in the womb.

This means that the mother has a repregnancy at the same time, and such a probability and situation are also 10 points rare.
