If you are living a multiple pregnancy, Congratulations, you are creating life twice. The miracle of life is a surprising fact, with certain doses of magic and mystery. When a woman experiences a multiple pregnancy, the aura of mystery that surrounds pregnancy is further increased. Therefore, you may be a little scared as the work will in any case be double, but still rewarding.
It is possible that you are wondering if your children will be twins or twins, even if they will be very similar and it will be difficult for you to recognize them. There are some differences in terms of gestation, which help to differentiate if the babies are twins or twins, we will tell you about them below. To find out if your children will be identical, you will have to wait until they are born to be able to verify it.
Twins or twins?
At the gestational level there are very clear differences To determine if the babies are twins or if they are twins:
The characteristics of the twins are:
They are also known as bivithelial, dizygotic, or fraternal twins. They start from the fertilization of two eggs by two different sperm. They can be of the same sex or have different sexes, in addition, they can look a lot or as little like two siblings born to different gestations. In the case of twins, there is a clear genetic influence and the physical traits of the mother, as well as fertility and assisted reproduction treatments.
Twins always gestate in different placentas and they also have different amniotic sacs. In the case of a twin or multiple pregnancy, there is a 70% chance that the babies will be twins. As with siblings born from different pregnancies, twins share 50% of genes. They can also share the blood group but it does not happen in all cases.
The characteristics of the twins are:
They are also called univitellines, monozygotic, or identical twins. The twins emerge from the fertilization of an egg by a sperm, the fertilized egg divides and gives rise to two babies. Twin brothers always have the same sex and also share an important physical resemblance, they are practically physically identical. In this case, there is no influence of genetic inheritance or any other possible factor.
In the case of twins, it is possible that they share the placenta and the amniotic sac, as well as it is possible that they have them singly in both cases. There is only a 30% probability that a twin pregnancy will result in identical twins, the highest percentage being twins. Twin brothers share 100% of their genesThey even share the same blood group.
Is it possible to know if they are twins or twins during pregnancy?
In the case that the babies are of different sex it will be much easier, since always in this case the children will be twins. But what happens when the babies are of different sexes? The type of placenta can also help to find out, although the results are not always conclusive.
If you want to find out during your pregnancy if your babies will be twins or twins, the only way to know is through a test called the zygosity test. This test consists of analyzing the zygotor, which is the result of the union of the ovum and the sperm.
The zygosity test
By analyzing the zygote, it is possible to find out if the twin pregnancy is about twins or identical twins. The case is a little more complicated when the pregnancy is of three or more babies.
The results could be the following:
- In the case of 2 babies They can be identical twins, twins or semi-identical twins in a very low percentage, since it is a very rare case.
- When there are 3 or more babies the case is complicated. The most common in the case of multiple pregnancy is that the babies are twins. It could also be the case that two identical twins and a twin were born. In very rare cases, as few as 2% of cases, triplets could be identical twins.
This test can be done during pregnancy, analyzing amniotic. But it can also be done in born children, with just a mucus sample the results would be obtained through DNA. Knowing these genetic traits can be very important in the case of possible complications or future illnesses.
