There is no relationship between the fact that the first child looks like the mother and the fact that the second child will have a boy or a girl. This claim lacks scientific basis and should not be listened to blindly. The male sex chromosome is XY, and the spermatozoa that divide and mature are called X spermatozoa and Y spermatozoa. Females have XX sex chromosomes, and when the egg divides and matures, it contains an X sex chromosome. Since males have 2 types of sperm and females have only 1 type of egg, the birth of a boy or girl depends on the type of sperm cells in the male. Therefore, the gender of the second child is not related to the length of the first child, etc. It is recommended that pregnant women should conduct pregnancy checkups on time after pregnancy and not overly believe in claims that lack scientific basis.
