Gametogenesis is defined as?

• A. Replication of DNA in germ cells
• B. Division of somatic cells
• C. Formation of a zygote
• D. Process by which meiotic divisions produce mature gametes

Answer: (D)

Gametogenesis is the production of mature gametes through meiotic divisions in the germ cells. Meiosis reduces the chromosome number from diploid to haploid and creates genetic variation, yielding sperm and eggs that can unite during fertilization. This distinguishes it from replication of DNA (which is just part of preparing for division), division of somatic cells (mitosis), and formation of a zygote (fertilization after gamete fusion). The idea is that gametogenesis encompasses the meiotic production and maturation of haploid gametes, such as sperm and eggs.
