What term describes cell division that occurs in the testes and ovaries and leads to the formation of gametes?

• A. Mitosis
• B. Gametogenesis
• C. Fertilization
• D. Meiosis

Answer: (D)

Meiosis is the specialized cell division that occurs in the testes and ovaries to form gametes. It reduces the chromosome number from diploid to haploid, producing sperm or eggs. This happens through two consecutive divisions (meiosis I and meiosis II) and results in four genetically diverse haploid cells, which is essential for sexual reproduction. By contrast, mitosis creates identical diploid somatic cells for growth and repair, not gametes. Fertilization is the fusion of two gametes, not a division. Gametogenesis refers to the overall process of forming gametes, with meiosis being the key division that actually generates the haploid gametes.
