After reading these sentences,How?Looks like we hear you say. Whether the baby in the womb is born as a boy or a girl, grows and looks exactly the same. The gender will be determined in the coming weeks.

Well, initially from our mother How can we explain that we were conceived in the same sex?

As we all know, when a man and a woman form a tiny human, the genetic information of both combines 50:50.

23 chromosomes from both men and women come together, and a selected pair of the total 46 chromosomes play a role in determining the sex of the baby. One from the mother and one from the father If 2X chromosomes are combined, the sex of the baby will be a girl.

If one of these chromosomes is Y, the baby is born male. So as a result it becomes male and female gender It is formed according to the genes of the mother and father.

In fact, the key point here is that the Y chromosome comes into play later, rather than immediately, during this combination.

In fact, the first five to six weeks of embryonic development are attributed only to the X chromosome, and babies whose sex will be female are only through the influence of the X chromosome It continues to grow from the embryo until it reaches full development.

In male babies, after this 5-6 week period, on the Y chromosome, A gene called SRY is activated and inhibits some features of the X chromosome. At the same time, male physiological characteristics such as testicles are imposed by genetic dominance.

However, if the SRY gene is not active, problems such as the formation of the clitoris instead of the penis occur. female phenotype and physical appearance will continue A situation arises and the baby becomes a girl.

Instead of the penis and the clitoris, the nipples are also formed according to this gender formation.

Nipples of the baby preparing to be born, During the critical 5-6 weeks before the SRY gene becomes active occurs. This means that we all have nipples, men and women, but women’s nipples are formed by different hormonal developments.

In short, all of us We begin life in the womb as women. If the fetus does not have a Y chromosome, the embryo will continue to develop as a female. However, if the Y chromosome is present, the male sex hormone testosterone limits full development of the breasts to the nipples only, and the clitoris also becomes the penis.
