1. Describe the main results of meiosis
Four haploid cells genetically different from each other and from parent cell.
2. What are the principle differences between mitosis and meiosis?
• Mitosis makes body (somatic) cells; meiosis makes gametes (sperm, egg).• Mitosis makes 2 cells, meiosis 4.• Daughter cells from mitosis genetically identical to parent cells; cells from
meiosis different.• Mitosis makes diploid (2N) cells, meiosis haploid (N)
3. What do the terms diploid and haploid mean?
• Diploid = 2 sets of chromosomes.
• Haploid = 1 set of chromosomes.
5. In human cells, 2N = 46. How many chromosomes would you expect to find in a sperm cell? Egg cell? White blood cell? Explain.
• 23• 23 • 46
Connecting Concepts. In asexual reproduction, mitosis occurs, but not meiosis. Which type of reproduction – sexual or asexual – results in offspring with greater genetic variability? Explain your answer.
• Sexual, because offspring get genes from 2 parents.
• In asexual reproduction offspring are genetically identical to parents.
