Detailed explanation-1: -At the end of meiosis, four haploid cells have been produced, but the cells are not yet gametes. The development of haploid cells into gametes is called gametogenesis. Spermatogenesis produces four haploid sperm cells, while oogenesis produces one mature ovum.
Detailed explanation-2: -Diploid cells within the testes undergo meiosis to produce haploid sperm cells with 23 chromosomes. A single diploid cell yields four haploid sperm cells through meiosis.
Detailed explanation-3: -So the parent (original) cell gives rise to four sex cells. 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.
