Take-Home Assignment #4 - Meiosis and Genetics due at Lecture Wednesday October 21.

After studying this material you should be able to:

1. Discuss the relationship between sex and reproduction, and compare sexual and asexual reproduction.

2. Draw a diagram that illustrates the relationships among the terms: chromosome, DNA, genes, chromatids, centromeres, homologous chromosomes (homologs), and alleles.

3. Recognize the essential elements of the process of meiosis.

4. Explain the role of meiosis in an organism's sexual life cycle.

5. Describe your own life history in terms of a general sexual life cycle.

6. Indicate where and when in your body meiosis occurs and describe what is produced by the process.

7. Compare the process of meiosis in human females and males.

8. Use common objects such as paper clips or scraps of paper to model the changes in number and movement of chromosomes during meiosis.

9. Compare the timing, location, numbers of cells, numbers of chromosomes, and genetic outcomes of mitosis and meiosis.
