every human being has 23 pairs of chromosomes. the egg contains 23 chromosomes and the sperm also contains 23 chromosomes. so only two births are possible because there is no chromosome left. then how a mother gives birth to the third child?

Every human being has 23 pairs of chromosomes. During cell division, the chromosomes separate and enter the daughter cells by the process of mitosis and meiosis in somatic and sex cells respectively. Everytime, a new individual is born, cell division occurs and the daughter cell has the equivalent number of chromosomes.
