Are twins a boy and a girl?
Dragon and phoenix refers to a kind of twins that are pregnant with male fetuses and female fetuses at the same time. Because the dragon and phoenix in the symbols of male and female represent male and female respectively, they are called \”dragon and phoenix twins\”. However, not every pair of twins can be born, and the causes and gender ratio of twins are also topics of great concern.
Causes of twins
There are many reasons for the birth of twins. One of the more common ones is that the fertilized egg splits into two embryos in the early stage. One embryo develops into a male fetus, and the other embryo develops into a female fetus. The whole process is like two embryos. The fertilized egg is conceived in the mother\’s body at the same time.
In addition, twins may also be caused by differences in maternal endocrine substances. For example, when the mother\’s body does not secrete enough oxytocin or the amount of secretion is insufficient, it can easily lead to insufficient uterine tension, which can lead to premature birth. Premature babies generally have smaller bodies, while twins are relatively larger, so the chance of twins is increased. .
Sex ratio of twins
The sex ratio of twins is not fixed. Data shows that the ratio of twins born is about 1:1000. According to statistical data, the male-to-female ratio of twins born to twins is about 1:1. There are no more dragon twins than phoenix twins or more phoenix twins than dragon twins. This is because twins are usually fertilized at the same time, and the number of fertilized eggs in males and females is equal, so the birth ratio will be the same.
The real dilemma of twins
Although twins, a rare birth phenomenon, have received widespread attention and research, in fact, there are still some difficulties in real life. First of all, twins are twins who need more careful care and upbringing after birth. Secondly, due to physical and gender differences, the growth environment of twins also needs to be different. However, if they grow up in different environments, it can easily lead to differences in their personalities and growth experiences.
Conclusion
Although twins are a rare type of twin, their birth has provided us with more in-depth knowledge about twins and human reproduction, allowing us to better understand the preciousness of life and love. At the same time, we also need to pay attention to the difficulties faced by twins in reality and provide them with a better growth environment and care so that they can grow up healthily.
