  3. Meiosis Practice Test Answer the following questions on the back of your review sheet.

  4. 1. Meiosis and mitosis are different because… • Meiosis produces 2 haploid cells • Mitosis produces 4 haploid cells • Meiosis produces 4 haploid cells • Mitosis produces 2 haploid cells

  5. 2. Haploid means • Happy • Half the number of chromosomes needed • Full set of chromosomes • Same as diploid

  6. 3. How many of the cells become the egg and sperm at the end of meiosis (in that order): • 1 and 3 • 2 and 4 • 1 and 4 • 2 and 3

  7. 4. Crossing over occurs in which phase? • Telophase I • Metaphase II • Metaphase I • Telophase II

  8. 5. How many times does a cell divide in meiosis? How many chromosomes in the end? • 2 and 23 • 2 and 46 • 1 and 46 • 1 and 23

  9. 6. Besides crossing over, what other step does meiosis do to help with genetic diversity? • Divides twice • Determines gender • Independent assortment • Occurs differently in men than women

  10. 7. How does the genetic content of cells resulting from meiosis and mitosis differ? • Mitosis they are different • Meiosis they are the same • No difference between meiosis and mitosis • Meiosis they are different

  11. 8. During which phase does the following happen: Cells undergo a round of DNA replication • Metaphase I • Anaphase II • Interphase • Telophase II

  12. 9. What does the picture represent? • DNA replication • Transcription • Independent assortment • Crossing over

  13. 10. What do the spindle fibers do? • A. pull apart chromosomes during anaphase • B. keep the structure of the cell • C. help with molecule transport • D. assist with DNA replication

  14. 11. Why is meiosis needed? • For asexual reproduction to occur • To decrease genetic diversity • For sexual reproduction to occur • To increase DNA replication

  15. Answers • C • B • C • C • A • C 7) D 8) C 9) D 10) A 11) C

  16. Important Reminders • Quiz Friday on meiosis • Meiosis packet due friday

  17. Test corrections SEPARATE SHEET OF PAPER!!! • Question # • Correct Answer • Where did you find the answer? (location and section #) • Why is that the correct answer? Need all four parts to have a complete test correction. This goes in as a separate assignment Retake if you got a 50 and below to get up to 50.5 (70%). All retakes must be complete by Thursday, 5/3
