Detailed explanation-1: -In the human reproductive process, two kinds of sex cells, or gametes (GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female’s reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat).

Detailed explanation-2: -Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm.

Detailed explanation-3: -Sperm cells are produced in men’s testicles and egg cells are produced in women’s ovaries. Sex cells are different from other cells in one special way: Put simply, they only have one half of the total amount of human genetic information.

Detailed explanation-4: -The nucleus of each sex cell contains half of the original genetic material. In men, these cells develop into sperm cells. In women, only one of the four sex cells becomes an egg cell that can be fertilized. During meiosis, it receives most of the cell body of the parent cell.

Detailed explanation-5: -Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
