Read each question carefully and answer to the best of your ability. Refer to the diagram provided for assistance.
1. Which of the following events occurs during Prophase I of meiosis?
Sister chromatids separate.
Homologous chromosomes pair up and crossing over occurs.
Chromosomes align at the metaphase plate individually.
Two diploid daughter cells are formed.
2. During which phase of meiosis do homologous chromosomes separate and move to opposite poles of the cell?
Prophase I
Metaphase II
Anaphase I
Telophase II
3. The process of involves the exchange of genetic material between homologous chromosomes during Prophase I.
4. At the end of Meiosis I, two cells are formed, each with half the number of chromosomes as the parent cell.
5. During Anaphase II, separate and move towards opposite poles.
6. Meiosis results in four genetically identical haploid cells.
True
False
7. The primary purpose of Meiosis II is to separate sister chromatids.
True
False
Match each event with the correct phase of meiosis.
8. Homologous chromosomes line up at the metaphase plate.
a. Prophase II
9. Nuclear envelope reforms around sets of chromosomes; cytokinesis occurs, resulting in two haploid cells.
b. Metaphase I
10. Sister chromatids align at the metaphase plate.
c. Telophase I
11. Chromosomes condense, and spindle fibers begin to form in two haploid cells.
d. Metaphase II
12. Describe the key differences between Anaphase I and Anaphase II of meiosis.
13. Explain the significance of crossing over in genetic variation.
