Chapter 6, Problem 16P
In Meselson and Stahl’s density shift experiments (diagrammed in Fig. 6.20), describe the results you would expect in each of the following situations:
| a. | Conservative replication after two rounds of DNA synthesis on 14N. |
| b. | Semiconservative replication after three rounds of DNA synthesis on 14N. |
| c. | Dispersive replication after three rounds of DNA synthesis on 14N. |
| d. | Conservative replication after three rounds of DNA synthesis on 14N. |

In humans, red-green color blindness is recessive and X-linked, whereas albinism is recessive and autosomal. What types of children can be produced as the result of marriage between two homozygous parents, a normal-vision albino woman and a color-blind, normal male?
In Drosophila, an X linked recessive mutation, scalloped (sd), causes irregular wing margins. Diagram the F1 and F2 results if a (a) scalloped female is crossed with a normal male; (b) a scalloped male is crossed with a normal female (assume the female is homozygous). Compare these results to what you would find if the trait was not sex linked.
Case Study—Ella
Ella has a family history of diabetes. She wants to follow a healthful eating pattern that can lower her risk for developing this condition. Her dietitian recommends a goal of 450 to 600 kcal per meal and advises Ella to follow the Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates and the Dietary Guidelines for Americans 2015-2020, which recommend limiting added sugar. She also recommends that Ella choose whole grains rather than processed grains. Ella decides to pack a lunch to take to work every day. This morning she’s making a sandwich for her lunch.
