Mitosis and Meiosis Review

Whiteboard Questions If a cell has 40 chromosomes, how many are in each cell at the end of meiosis? Mitosis? T/F: Mitosis creates 2 different cells T/F: A difference between meiosis & mitosis is that meiosis occurs in gametes and mitosis occurs in somatic cells. What is 1 way variation is provided in meiosis?

IS the following description meiosis or mitosis. 6 IS the following description meiosis or mitosis? 6. Two cell divisions 7. Occurs in gametes 8. Half the original chromosomes 9. Homologous Chromosomes pair up 10. Creates identical cells 11. Four daughter cells 12. Same #of chromosomes in each cell at end

13. Which letter in Figure 1 represents meiosis. 14 13. Which letter in Figure 1 represents meiosis? 14. Which letter in Figure 1 represents mitosis?

Which stage of meiosis is listed below. 15 Which stage of meiosis is listed below? 15. homologous chromosome line up in the center of the cell 16.homologous pairs are pulled to ends of the cell 17. 4 haploid daughter cells form 18. cells undergo a round of DNA replication 19. 2 daughter cells form 20. individual chromatids move to each end of the cell 21. crossing-over (if any) occurs
