Questions and Answers

What is the primary difference between mitosis and meiosis?

  • Mitosis occurs in somatic cells, while meiosis occurs in gametes.
  • Mitosis results in four daughter cells with half the number of chromosomes, while meiosis results in two daughter cells with the same number of chromosomes.
