The twenty-third pair of human chromosomes determines gender. In men, these are the X and Y chromosomes, and in women, these are the X and X chromosomes. The eggs can be fertilized after leaving the ovary. If the egg is fertilized by a sperm, a zygote is formed. If this does not happen, the egg leaves the woman’s body and the formation of new eggs begins. Sperm cells form in the testes. Any germ cells contain half of the chromosome set. Therefore, the zygote has a complete chromosome set.
