Meiosis is a specialized form of cell division that occurs in organisms that reproduce sexually. The types of cells that undergo meiosis are referred to as germ cells, which are found in the reproductive organs (the testes in males and the ovaries in females).
During meiosis, a diploid germ cell (containing two sets of chromosomes) undergoes two rounds of division, known as meiosis I and meiosis II. This process ultimately produces four genetically distinct haploid cells, each containing one set of chromosomes. In males, meiosis results in the production of four sperm cells, while in females, meiosis typically produces one viable egg cell (ova) and three polar bodies that generally do not participate in fertilization.
In summary, meiosis occurs in germ cells and produces haploid gametes: sperm in males and eggs in females.
