Mitosis, Meiosis, & Cell Division Practice Problems
21. The product of meiosis is:
A. Two genetically identical daughter cells
B. Two genetically unique daughter cells
C. Four genetically identical daughter cells
D. Four genetically unique daughter cells
22. During what phase of meiosis to sister chromatids separate?
A. Anaphase I B. Anaphase II C. Both Anaphase I & II
23. When does crossing over occur?
A. Prophase I B. Prophase II C. Both Prophase I & II
25. What is the chromosome number of the diploid cell pictured to the right?
A. 2n = 3 B. 2n = 6 C. 2n = 12
26. What stage of cell division is represented by the diploid cell pictured to the right?
A. Metaphase of mitosis B. Metaphase I
C. Metaphase II
27. When is a non-disjunction most likely to occur during egg formation?
A. Anaphase I B. Anaphase II C. Equally as likely during Anaphase I & II
28. Which of the people listed below is/are most at risk for producing a gamete with a
nondisjunction?
Alex, male, 20 years old Verna, female, 22 years old
Gustavo, male, 45 years old Shareem, female, 43 years old
A. Shareem is most at risk
B. Gustavo is most at risk
C. Both Gustavo and Shareem are equally at risk
D. Both Shareem and Verna are equally at risk
E. All of the people listed are equally at risk
29. What happens to a cell which does not pass the G1 checkpoint?
A. It dies via apoptosis
B. It enters the S phase of the cell cycle
C. It enters the G0 phase of the cell cycle
D. It enters the G2 phase of the cell cycle
30. When is a non-disjunction most likely to occur during sperm formation?
A. Anaphase I B. Anaphase II C. Anaphase I & II are equally as likely
In females, non-disjunctions are more common during Anaphase I and much rarer in
Anaphase II. However, in males, non-disjunctions are equally as rare in both Anaphase I
and Anaphase II.
