The probability of getting pregnant with twins is very low, so it's like winning a big prize, so people are very excited about getting pregnant with twins. There are still quite a few twins nowadays. Twins can have one placenta or two placenta. So, what is the probability of having twins with two placenta? This article will provide an answer.
Are two placenta twins twins
Gender cannot be determined, but it can be confirmed that they are twins. Because a twin with one placenta is a monozygotic twin, while a twin with two placenta is a dizygotic twin. Twins are divided into monozygotic twins and dizygotic twins. Homozygotic twins divide into two cells after fertilization of one egg, and continue to develop into two fetuses, while both fetuses use the same placenta for survival. So, identical twin fetuses have the same blood and gender characteristics, and their facial features, body shape, physique, intelligence, etc. are also very similar.
Heterozygotic twins are women who release two eggs at once, fertilize them, and implant them in the uterus. So, the gender of fraternal twins may not necessarily be the same. But the probability of fraternal twins occurring is particularly low compared to monozygotic twins. So there are fewer twins with twins. It is recommended that you go to a regular hospital for further comprehensive examinations. In fact, whether it is a boy or a girl, as long as the baby grows up healthily, it is the most important. It is even more difficult to conceive twins, so it is necessary to do more examinations to ensure the healthy development of the baby.
After pregnancy, whether it is one or twins, a boy or a girl, it doesn't matter because it has already been determined and cannot be changed. The only way is to strengthen nutrition and ensure their healthy development in the womb. I always think that this is not good for the fetal development.
What is the probability of having twins
Twins are identical twins, while twins are fraternal twins. In very rare cases, identical twins may have one male and one female, but both men and women usually have chromosomal or genetic abnormalities. From 1961 to 2000, medical literature has reported at least four cases of identical twins of different genders. The so-called monozygotic twins refer to the situation where a fertilized egg divides into two embryos during fertilization, with the same sex and genes, and the probability is extremely low. Heterozygotic twins refer to the situation where two egg cells implant in the female uterine cavity during fertilization, and fertilization occurs simultaneously, forming two embryos with their own placenta and different genes.
The appearance of fraternal twins is different. Different from identical twins. The country with the highest probability of having twins in the world is between 10% and 15%, while the probability in China is around 5%. The probability of having twins is much smaller, with a 25% chance of having twins who are twins. Because in general, the female partner only releases one egg per month, but in a few cases, she may release two eggs. If both eggs are fertilized, there is a chance of having twins, so basically, those who give birth to twins are very lucky.
A twin must have two placenta, but the two placenta can also be of the same gender. Just because there are two placenta, it cannot be determined that it is a twin. The chance of conceiving a twin is relatively small, and it can only rely on the favor of heaven to have a twin.
