Can fortune-telling calculate the birth of boys and girls?

How can there be such a mother-in-law after all this time?

People still believe in fortune telling, don't they?

=

Even if you give birth to a boy or a girl in the hospital, you can't see it. Does your mother-in-law believe what the fortune teller said? Did the fortune teller give a reason?

Sister, don't doubt it. You can't believe it at all. It is impossible to detect boys and girls, and the probability is 50/50 ~

And has decided to have boys and girls =

=

Female chromosome XX, male XY.

Mom provides 22 pairs of chromosomes plus one pair of sex chromosomes. The sex chromosome must be X, and there are also 22 pairs of chromosomes at Dad's place, plus one pair of sex chromosomes. But the sex chromosome may be X or Y. If an egg is combined with sperm containing X, the baby is a girl, and if it is combined with Y, it is a boy.

So even girls have nothing to do with you. Tell your mother-in-law to find her son. . .

The most important thing is, how can we prefer boys to girls? It's 2 1 century. . . =
