2. 2b. Compare the chromosomes of a diploid cell to a collection of shoes in a closes. How are they similar? What would make the shoe collection comparable to the chromosomes of a haploid cell? 2b. Shoes are in pairs as are chromosomes in a diploid cell. A “haploid” shoe collection would have only one shoe of each kind. Diploid: Haploid:

3. p. 329 A.Q. 2b, 3b, 4ab 3b. Is there any difference between sister chromatids and homologous pairs of chromosomes? Explain. 3b. The sister chromatids are identical because one is a copy of the other. The homologous pairs are not identical; one chromosome comes from the mother and one comes from the father.

4. p. 329 A.Q. 2b, 3b, 4ab 4a. How does the principle of independent assortment apply to chromosomes? 4a. Chromosomes assort independently. 46 chromosomes? 5 x 10 57 possible combinations!

5. p. 329 A.Q. 2b, 3b, 4ab 4b. If two genes are on the same chromosome but usually assort independently, what does that tell you about how close together they are? 4b. It tells us that the two genes are located very far apart from each other.
