What does it mean to have a daughter in spring? What does it mean to have a daughter in spring?

1. Giving birth to a girl in spring is spring divination and giving birth to a girl. This way of judging the sex of the fetus is unscientific.

2. The sex of fetus is determined by chromosome composition. There are 23 pairs of 46 chromosomes in human germ cells, of which 22 pairs are autosomes, 1 pairs are sex chromosomes, and female sex chromosomes are XX. The male sexual characteristic is XY. When the sperm carrying X chromosome is combined with the egg, a girl is obtained; When the sperm carrying the Y chromosome is combined with the egg cell, it is a boy. The number of sperm containing X and Y chromosomes is roughly equal, so there is a 50% probability of the sex of the fetus. So we can't judge men and women by this.
