Questions and Answers

What is the primary objective of meiosis?

  • To promote asexual reproduction in organisms
  • To ensure genetic diversity in offspring (correct)
  • To increase the number of chromosomes in daughter cells
  • To produce genetically identical daughter cells

    • During which phase of meiosis do dynamic changes in cellular components occur?

  • Prophase I (correct)
  • Anaphase II
  • Metaphase I
  • Telophase II

    • What is the outcome of meiosis in terms of the number of daughter cells and chromosomes?

  • Four nonidentical daughter cells, each with half the number of chromosomes of the parent cell (correct)
  • One daughter cell with double the number of chromosomes as the parent cell
  • Two identical daughter cells with the same number of chromosomes as the parent cell
  • Four identical daughter cells with double the number of chromosomes as the parent cell

    • What is the main physiological role of meiosis in sexual reproduction?
