Who genetically determines the birth of a boy or a girl?

Who decides to have a boy or a girl? Star Awareness Project

Meng Xinbao's parents should know, who decides to have a boy or a girl?

It is mainly decided by the father, since only the father has the Y chromosome.

The birth of a boy or a girl is chromosome-determined.

It's up to the father to decide. Because it is determined by the x and y of the genes.

It must have been the father who decided that the father had a y in him

Generally speaking, it is genetically determined and random, so don't worry too much about it.

It was determined by the man. Mainly look at its chromosomes. Is it X or Y?

Of course, the father, only the male has the Y chromosome.

Those who say that the father decided that the biology is good? What does it have to do with men? It's a matter of probability, okay.

The main thing is that the father decides. The father has a Y chromosome.

3. Genes can't determine genderNow people who have attended nine years of compulsory education know that whether a child is male or female depends on anyone, it is just a matter of probability, and genes cannot determine gender. Nowadays, the public's mind is also relatively open-minded, whether it is a boy or a girl, it is the baby that every family wants the most. And now families are more inclined to like girls, because girls will add more happiness to the family.

Personally, I don't feel that the birth of a boy or a girl is generally determined by the genes of the two parents, and it is related to the physical condition of the two parents.

Yes, having a boy or a girl is determined by the father's genes, because the father's genes are the X chromosome and the Y chromosome, so the sex of the child is determined by the father's genes.

Yes. It is decided by the man to give birth to a boy or a girl, and the man gives the X chromosome, and a daughter is born. The Y chromosome gives birth to a son.

Regarding the birth of a boy and a girl, it has always been a topic of great concern to everyone, especially for families preparing for pregnancy, the birth of a boy or a girl depends on the man or the woman? Who is genetically determined? Does it depend on the boy to have a girl? Let's find out!

According to science, it should be up to the man to have a boy or a girl. It is mainly determined by chromosomes.

It is related to the status of men in the family, such as women are strong and unreasonable, and men are mentally weak and basically give birth to girls. Otherwise, it's the other way around. You can observe whether the colleague's family is this regular.

It turns out that the decision to have a boy or a girl is not up to the man, so I've been mistaken.

It is determined by both the man and the woman, and the genes are on the chromosomes, while the chromosomes are half from the father and half from the mother.

Plant melons and get melons, plant beans and get beans, what you get is determined by the seeds, and it doesn't count.

It's about men.

v 134 consultation 2756 to understand 1060 birth boys, ancestral secret recipes, 100% success, has become 65 cases.

Fundamentally, it's up to the man to decide, but how? I have summarized for a long time and concluded that the contrast between the high and low levels of the two hormones in both men and women causes natural selection for the sex of the fetus.

Generally speaking, men with strong levels of male hormones and high levels of female estrogen are more likely to give birth to boys; On the contrary, it is easy to give birth to girls; Others can be male or female. By regulating the hormone levels of both parties, the purpose of artificially selecting the sex of the fetus can be achieved. Welcome to private chat**.

The birth of a boy or a girl is mainly determined by the male's genes. Sex chromosomes are directly related to sex determination. At the genetic level, the SRY gene is generally used as a sex-determining gene, that is, if you have the SRY gene, you will develop into a boy, and if you do not have a SRY gene, you will develop into a girl.

The SRY gene, the sex-determining gene of males, refers to the gene segments on the Y chromosome that specifically determine the sex of the male of an organism. The human SRY gene is located in a protein that contains only one exon and no introns, and the transcription unit is about long and encodes a 204 amino acid protein.
