What is the final result of meiosis?

• A. 2 genetically different daughter cells
• B. 4 genetically different daughter cells
• C. 4 genetically identical daughter cells
• D. 2 genetically identical daughter cells

Answer: (B)

Meiosis ends with four haploid daughter cells, each carrying a unique combination of alleles. This happens because meiosis uses two rounds of division after a single round of DNA replication. During prophase I, crossing over shuffles genetic material between homologous chromosomes, creating new allele combinations. Then, as homologous chromosomes separate in metaphase/anaphase I (independent assortment), different parental chromosomes get distributed into gametes. In meiosis II, the sister chromatids finally separate, giving four distinct haploid cells. In humans, each of these cells has half the original chromosome count, typically 23, and they are genetically diverse due to the recombination and assortment that occurred earlier.
