The mother is a girl in the womb, and before being born a boy how to explain

How could it be, I made a mistake before.

Of course, it's up to Dad to decide. Because mom only has the X chromosome and dad has the Y chromosome. Giving birth to a girl is the X chromosome, and giving birth to a boy is the Y chromosome.

It's up to the dad, if the dad's gene is an X chromosome, it's a girl, if it's a Y chromosome, it's a boy.

Modern scientific research has shown that males have one X and one Y chromosome, and females have two X chromosomes. When X and chromosome combine with X chromosome, a girl is born; When the X chromosome and the Y chromosome are combined, a boy is born. Only the father of the child has the Y chromosome in his body, so it is up to the father to have a child.

In ancient times, when science and technology were not developed, such backward concepts continued for thousands of years, causing great harm to women. I believe that having children and daughters is all passed down from generation to generation, and they are all the continuation of their own bloodline in this world, there is no difference. What's more, having children and daughters is completely decided by the father of the child, and has no half-dime relationship with the mother.

Preference for sons over daughters, believing that only having sons is the inheritance of the family lineage" is a bad feudal custom, and New China has criticized it and put forward the correct concept of "equality between men and women." Indeed, women are also the backbone of social production and should not be underestimated. What's more, patriarchy will only bring about a serious imbalance in the ratio of men and women, and what should I do if a group of "bald guys" can't marry a wife when the time comes?

Therefore, you must cherish the birth of children and daughters!

To sum up, it is the same to have a child and a daughter, and it is up to the father of the child to decide whether to have a boy or a girl.

It is up to the father to decide whether to have a boy or a girl, and many of them give birth to daughters, so it must have something to do with the father.

It all matters, the man decides the boy or the girl, and the woman decides whether to accept the boy or the girl.

Depends on the father

Because males have X and Y chromosomes in their sex chromosomes, females are xx. If a male's X chromosome and a female's X chromosome combine to give birth to a girl, but a male's Y chromosome and a female's X chromosome combine then a boy is born!

Heredity is a combination of half of the parents, including the blood type combination. There are two types of male sex genes, x and y, which are combined with female sex genes x and x to form male x+y and female x+x genders, with a probability of about 50% each.

Females have only two X's on chromosomes

The male chromosomes are x and y

So it's a man's decision. The chromosome of the male is y and the entry is male x entry is the female.

To be honest, this question is a bit two!

Sex is determined by chromosomes, xx for women and xy for men. Women don't have a Y chromosome at all, so it's up to the man to decide whether a boy or a girl is a man, and it doesn't matter if a woman's belly is angry or not!

Does the landlord understand?

It's Dad, it's biological, it should be whether the Y chromosome is inherited or not, and Mom is X, so it doesn't matter.

Dad decided, it's common sense.
