Chapter 15, Problem 18P
| a. The original constitutive operator mutations in the lac operon were all base changes in o1. Why do you think mutations in o2 or o3 were not isolated in these screens? |
| b. Explain how a mutagen that causes small insertions could produce an oc mutation. |
| c. Would the oc mutation described in part (b) be sensitive to laclS? Why or why not? |

3.
In the tomato, red fruit (O+) is dominant over orange fruit (0), and yellow flowers (W+) are dominant over white
flowers (w). A cross was made between true-breeding plants with red fruit and yellow flowers, and plants with
orange fruit and white flowers. The F₁ plants were then crossed to plants with orange fruit and white flowers, which
produced the following results:
a.
b.
333 red fruit, yellow flowers
64 red fruit, white flowers
58 orange fruit, yellow flowers
350 orange fruit, white flowers
Conduct a chi-square analysis to demonstrate that these two genes DO NOT assort independently. Make sure
to interpret the P value obtained from your chi-square test.
Calculate and provide the map distance (in map units) between the two genes.

Investigation: Is a dog more closely related to a coyote or a wolf?
Gray Wolf
Species Name: Canis lupus
Color: Light gray to black
Size: 80-120 pounds, 2.5 feet tall
Appearance: broad snout, round ears, long tail
Coyote
Species Name: Canis latrans
Color: Light gray to brown
Size: 20-50 pounds, 1.5 feet tall
Appearance: narrow snout, pointed ears, long tail
Dog, Alaskan Malamute
Species Name: Canis lupus familiaris

1. Examine the images and descriptions above.
Underline any similarities between the dog and the wolf.
Place a star
next to any coyote traits that are similar to the dog.
2. Based on appearance alone, which do you think is the most closely related to a dog?
