It is highly suggested that you work on these on your own, but they do not have to be handed in and will not be graded. Your Biomentors will hold sessions every week for discussion of the topics in these sets, but neither they nor your professor will provide you with the answers. Watch the following online animations and use them to help you answer the questions below: Meiosis http://media.pearsoncmg.com/pcp/ph_blast/animations/genetics/cell_division/meiosis/me iosis_w.htm Compare Meiosis to Mitosis http://media.pearsoncmg.com/pcp/ph_blast/animations/genetics/cell_division/mitosis_me iosis_comp/mitosis_vs_meiosis_w.htm 1. Fill in the following schematic of meiosis: 2 Cells in Metaphase II Cells at Telophase II Cells at the end of Meiosis Cells in Metaphase II Cells at Telophase II Cells at the end of Meiosis 2. Is the cell in the image to the left in mitosis or meiosis? What stage of mitosis or meiosis is this cell in? 3. This cell has four chromosomes when it is diploid. Is the cell in mitosis or meiosis? What stage of mitosis or meiosis is it in? 3 4. This cell has four chromosomes when it is diploid. Is the cell in mitosis or meiosis? What stage of mitosis or meiosis is it in? 5. What are the major differences between meiosis and mitosis? 6. How many times does interphase occur during meiosis? a. 0 b. 1 c. 2 d. 3 7. Which of the following are key features of S phase?

Which of the following are events in Prophase I in the order that they occur? a. Chromosomes replicate then synapse b. Chromosomes condense, recombine then synapse c. Chromosomes replicate, condense, recombine then synapse d. Chromosomes synapse and then recombine 9. Synapsis that occurs during Meiosis I is mediated by the _____________ complex. 10. Which of the following occur during Metaphase I? (circle all that apply) a. Chiasma disappear b. chromosomes migrate to the middle of the cell c. homologues segregate from each other d. the meiotic spindle breaks down 11. Which of the following occur during Metaphase II?
