Questions and Answers

What is the purpose of meiotic division?

  • To generate male and female gametes. (correct)
  • To maintain the same number of chromosomes as the mother cell.
  • To replicate DNA so each chromosome is duplicated into sister chromatids.
  • To reorganize microtubules into a new cytoskeleton.

    • What process in meiotic division ensures genetic diversity?

  • Replicating DNA to duplicate chromosomes.
  • Cytokinesis to form daughter cells.
  • Reorganizing microtubules into a new cytoskeleton.
  • Synapsis, crossover, and chiasma. (correct)

    • How many viable sperm do men produce at the end of meiosis?

  • 3
  • 4 (correct)
  • 2
  • 1
