Monochorionic diamniotic twins: twins
Monochorionic diamniotic twins twins is the most frequent case of identical twins. To be more precise, the twins. But in medicine, they are still called twins. The term "monochorionic" means that the kids have a shared placenta. Of course, it is easy to guess that it's not very good. It often happens that one fruit, growing faster, suppress the other, absorbing more nutrients. In the end, children are born with a significant difference in weight.
Types of twins
Happy mother expecting twins, always intriguing question about whether her small children to resemble each other, or their similarity is insignificant. Unfortunately, it is always a surprise. In advance and with absolute certainty to diagnose the development of twins can not no doctor. But if precisely to determine what twins in women, it will be possible to make a rather bold predictions about kids and their degree of similarity. To do this, especially in the early stages of pregnancy, it's easy.
There are only two types of twins: monozygotic and dz. In turn, they can be divided into subspecies. Actually, what the twins is the mother largely determines the complexity of pregnancy, risks and complications associated with the period of gestation and generic the process. Found that monochorionic diamniotic twins twins (photos of the twins you can see in this article) is found in the development of babies from one egg more often.
"Monozygotic twins" called the twins who developed from one egg. To occur such division of the zygote may be at different time. That is why monozygotic twins are of several types. Depending on when a split occurred, there are biamniotic, bicolandia, Diagnosticheskie, dioralyte twins. As a rule, with some exceptions, monozygotic twins of the same sex, or boys, or girls. However, they very much resemble each other, and the differences in appearance they appear only with age.
The types of monozygotic twins
Monochorionic diamniotic twins twins most common. It occurs 4-8 days after fertilization of the ovum. But it should happen strictly before the zygote is implanted in the uterine wall.
The term "monochorionic" means that both the fetus get nourishment from the same placenta. This, of course, is accompanied by the risk of some complications. Almost always after birth of the kids, one a baby a few larger and more developed than the second. This is because he, suppressing his little brother or sister, consumes a greater amount of nutrients. If a woman will not get sufficient amount of minerals and vitamins, the second baby may not survive.

Monoamniotic monochorionic twins
Monoamniotic monochorionic twins is one of the most dangerous. In this case, the separation occurs 8 to 12 days after fertilization. Usually this happens in the period when the zygote is implanted in the endometrium. The result is that both the fetus not only share a placenta but the amniotic sack.
Of course, monochorionic diamniotic twins twins is dangerous, but in the case of monoamniotic it is associated with the likelihood of even more complications. For example, children may become entangled in the umbilical cord of each other. Moreover, this pregnancy gives a large number of deviations. The most dangerous is the birth of conjoined twins. But if the separation will occur in due time, and pregnancy will be without complications, the babies born will have the same gender and blood type. And to distinguish their childhood will be difficult, even her own parents.
Rasnoavei twins are referred to as "dz". They have not only every type of amniotic SAC, but with their own placenta. In General, this is what distinguishes the twins from the twins. They should not resemble each other appearance. Blood can also vary. In the case of dz twins born children can be both same-sex and opposite-sex. They are like brothers and sisters born from the same parents but at different times.
