The birth of a boy or a girl is mainly affected by the male chromosome and carries a certain degree of random probability.
1. Male: Modern medicine has proved that the birth of a boy and a girl is mainly determined by the sperm of the male party. The sperm of the male party has two types of chromosomes, 22+X or 22+Y, and after combining with the egg of the female party, it will form an XY fertilized egg and an XX fertilized egg respectively, and the XY fertilized egg is a boy and the XX fertilized egg is a girl. Three daughters in a row represents a continuous contribution of 22+X chromosomes from the male partner.
2. Randomness: the chances of 22+X or 22+Y chromosomes appearing at the time of the male partner’s birth are 1:1, and the chances of natural fertilization of male and female fetuses are also 1:1, which is very fair. The birth of three daughters in a row is a random probability, and there is no human method to intervene.
In addition, it is recommended that the sex of the child be viewed scientifically.
