Chapter 10.1 - Meiosis
1. Meiosis can help explain why you have inherited certain characteristics from your parents. Write down some
characteristics you have inherited from your own parents.
2. Explain how DNA, chromosomes and genes are related.
3. What are gametes?
4. Identify three characteristics that are the same in each member of a pair of homologous chromosomes. Name one
thing that is different.

5. Use the words haploid cell, diploid cell, and fertilization together in a sentence.
6. How many cells are produced at the end of Meiosis?
7. How does the number of chromosomes produced at the end of meiosis compare with the number of chromosomes
found in the original parent cell?
7a. The diploid cells in a female bullfrog contain 26 chromosomes. How many chromosomes would be found in
each egg cell produced by that frog?
8. Describe the process of crossing over.
9. What is the end result of crossing over?
10. Sketch what happens to genes on chromosomes when crossing over occurs.
11. In which phase of meiosis does crossing over occur?
12. Compare meiosis and mitosis by filling in the chart below.
Mitosis
Number of DNA replications
Number of cell divisions
Number of daughter cells
Chromosome number of daughter cells.
13. Explain how meiosis creates genetic diversity.
