Where does meiosis occur?

• A. Liver and kidneys
• B. Bones
• C. Muscles
• D. Sex cells, ovaries and testes

Answer: (D)

Meiosis is the division that creates gametes with half the chromosome number, and it happens in the organs that produce sex cells—the ovaries in females and the testes in males. Those tissues specifically undergo meiosis to generate sperm and eggs for sexual reproduction. In contrast, tissues like the liver, kidneys, bones, and muscles divide by mitosis for growth and repair, not for producing gametes. So the process occurs in the sex organs—the ovaries and testes that produce the sex cells.
