Explain how asexual reproduction is different from sexual reproduction.
How is the sexual life cycle of animals different from that of plants? of fungi?
What is the relationship between homologous chromosomes?
From an evolutionary perspective, why do the stages of meiosis resemble the stages of
mitosis?
5. Explain what happens during crossing over and when it occurs in meiosis.
6. How is metaphase I different from metaphase of mitosis?
7. What DOES NOT happen between meiosis I and meiosis II?
8. Explain why sexual reproduction increases variation among offspring much more than
asexual reproduction does.
9. How many possible genetic variations can be produced during meiosis and sexual
reproduction?
10. Describe the process of karyotyping and why it is done.
11. How is sexual reproduction related to gender determination in mammals?

interphase, how many chromosomes will the following cells have?
a. after S phase of interphase.
b. a daughter cell immediately following cytokinesis I of meiosis.
