What is the outcome of Meiosis II?

• A. Formation of two diploid cells
• B. Formation of four haploid cells
• C. Genetic recombination
• D. Replication of DNA

Answer: (B)

The outcome of Meiosis II is the formation of four haploid cells. During Meiosis II, the two haploid cells produced in Meiosis I undergo a second round of division, similar to mitosis, where the sister chromatids are separated and pulled to opposite poles of the cells. This results in four genetically distinct haploid cells, each containing half the number of chromosomes as the original diploid cell. This process is crucial in sexual reproduction as these haploid cells become gametes (sperm or eggs), which contribute to genetic diversity in offspring through fertilization. Each of the resulting haploid cells has a unique combination of alleles due to the independent assortment and potential crossing over that occurred during Meiosis I, further enhancing genetic variation.
