Algorithms for boys and girls born at one month and two years old.

The one-month two-year-old male and female algorithm refers to the lunar calendar, two-year-old refers to the imaginary age, and one-month two-year-old or two-month one-year-old is pregnant and gives birth to a boy, and vice versa. This algorithm has no scientific basis. Giving birth to boys and girls is related to human chromosomes. When sperm and egg cells combine, both men and women provide a chromosome, and the woman provides X. If the man provides X, a girl will be born. If the man provides y, the probability of giving birth to a boy is the same.
