summary

Many women who give birth for the first time experience some pregnancy for the first time, so it is inevitable that they will not know. In particular, many people are confused about whether they have boys or girls. Now let's introduce the problem of giving birth to boys and girls in detail.

What's the difference between boys and girls

First, many people generally use the prediction table for boys and girls. It is based on the female. The age is calculated according to the imaginary age at the time of conception, that is, the first year at that time plus one year. It is listed in the vertical column of the table. The month of conception is calculated according to the lunar month, and it is listed in the horizontal column of the table. The intersection of the mother's virtual age and the month of conception is the sex of the fetus, so as to achieve the effect of predicting the sex of the fetus.

Second, the determination of gender depends on the "sex chromosomes" in the "germ cells" of parents' bodies. Chromosome is a kind of rod-shaped body contained in the nucleoplasm of nucleus, which is made up of DNA and protein. This can be achieved through medical tests.

Third: the sex of the fetus depends on which sex chromosome the father's sperm carries into the egg. To put it more popularly, it means "sow melon and reap melon, sow beans and reap beans". Therefore, the decision-maker of giving birth to boys and girls can only be the husband, not the wife. In fact, it is an accidental event.
