Exercise 2

You will need to understand solved problem S4 to answer this question. The gene for coat color in rabbits can exist in four alleles termed C (full coat color), c ch (chinchilla), c h (Himalayan), and c (albino). In a population of rabbits in Hardy-Weinberg equilibrium, the allele frequencies are
C = 0.34
c ch = 0.17
c h = 0.44
c = 0.05
Assume that C is dominant to the other three alleles. c ch is dominant to c h and c , and c h is dominant to c.
A. What is the frequency of albino rabbits
B. Among 1000 rabbits, how many would you expect to have a Himalayan coat color
C. Among 1000 rabbits, how many would be heterozygotes with a chinchilla coat color
