Question 1. In humans, black eye color is dominant to blue eye color and tall is dominant to short. The loci that determine height and eye color are linked and separated by a distance of 21 m.u. Using E and H as the genes for eye color and height, respectively, determine the phenotypes and proportions of the progeny from each of the following crosses. Show your work.

a. EH/eh x eh/eh

b. Eh/eH x eh/eh

c. A cross between Eh/eH x eh/EH was performed, and 100,000 progeny were collected. How many of the 100,000 progeny are expected to be short with blue eye-color?

Question 2. 4. Assume A and B are linked with 30% recombination. A pure-breeding dominant female is crossed with a pure-breeding recessive male, and the F1 is test-crossed to form the F2. Diagram this cross by writing out the parental genotypes, the F1 genotype & ratios, and the F2 genotypes and ratios.
