Questions and Answers

During meiosis, what is the final ploidy of the resulting cells?

  • Diploid (2 sets of chromosomes)
  • Triploid (3 sets of chromosomes)
  • Haploid (1 set of chromosomes) (correct)
  • Tetraploid (4 sets of chromosomes)

    • What is the main difference between mitosis and meiosis in terms of chromosome separation?

  • Both homologous chromosomes and sisters separate in mitosis
  • Homologous chromosomes separate in meiosis, sisters separate in mitosis (correct)
  • Sisters separate in meiosis, homologous chromosomes separate in mitosis
  • Both homologous chromosomes and sisters separate in meiosis

    • What is the significance of crossing over in meiosis?

  • It leads to the production of genetically identical gametes
  • It ensures the formation of diploid cells
  • It prevents the separation of sister chromatids
