Questions and Answers

What is the main difference in genetic outcomes between mitosis and meiosis?

  • Mitosis involves genetic recombination, while meiosis does not.
  • Mitosis leads to the formation of haploid cells, whereas meiosis produces diploid cells.
  • Mitosis occurs in haploid cells only, while meiosis occurs in diploid cells only.
  • Mitosis produces genetically identical cells, while meiosis results in genetically diverse gametes. (correct)
