11.1 Questions
1. After asexual reproduction (mitosis) produces offspring; how does the offspring’s DNA
compare to the parents?
2. After sexual reproduction (meiosis)produces offspring; how does the offspring’s DNA
compare to the parents?
3. How does the chromosome number compare to the parent after mitosis? After meiosis?
4. Since humans have 23 pairs of chromosomes (46) in all our body cells – what is our diploid
number? What is our haploid number?
5. Why does the number of chromosomes need to be reduced in order for sexual
reproduction to make viable offspring?
11.2 Questions
6. What occurs during each stage of meiosis?
7. Why do the stages of meiosis seem to happen twice?
8. How does the function of mitosis differ from the function of meiosis?
9. Define crossing over.
10. Describe the Law of Independent Assortment (during meiosis only)
11. Describe the Law of Segregation (of chromosomes during cell division)
12. Why does independent assortment only apply to meiosis and segregation apply to both
mitosis and meiosis?
13. Explain at least 3 ways that genetic variation can occur.
14. Why is sexual reproduction an advantage to some species and situations?
15. Why is asexual reproduction sometimes an advantage?
16. List ways that mitosis and meiosis are alike
17. List ways that mitosis and meiosis are different.
18. Write a good paragraph (at least 5 points) that compare and contrasts (the process/ steps/
outcomes and functions of) mitosis and meiosis.
