Cell division that produces sex cells is

• A. Cytokinesis
• B. Mitosis
• C. Meiosis
• D. Binary fission

Answer: (C)

Producing sex cells requires halving the chromosome number and generating genetic diversity. Meiosis accomplishes this by undergoing two rounds of division after one round of DNA replication, producing four haploid gametes. It also includes crossing over and independent assortment, which shuffle alleles and increase variation among offspring. In contrast, mitosis preserves the chromosome number to make two identical diploid cells for growth or repair, and binary fission is a simple division seen in prokaryotes that doesn’t produce gametes. Cytokinesis is the final splitting of the cytoplasm and occurs in both mitosis and meiosis, but it doesn’t by itself define sex-cell production.
