Chapter 8, Problem 1AAATB
Two parents both have brown eyes, but they have two children with brown eyes and two with blue eyes. How is it possible that two people with the same eye color can have children with different eye color? If eye color in this family is determined by differences in genotype for a single gene with two alleles, what percentage of the children are expected to have blue eyes? If the ratio of brown to blue eyes in this family does not conform to expectations, why does this result not refute

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.

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?

Yourequations should be of the form: dCglitazone /dt = something, or dMglitazone /dt = something. Your model shouldinclude three compartments: the gut, the plasma, and the fatty tissues.
