Suppose that a particular gene that controls coatcolor in dogs is controlled by four alleles in the population.These alleles are called cch (chinchilla dog),cd (white dog with dark eyes),cb (pale gray dog) and c (albino dog).The alleles are given from the most dominant to the most recessive.Let’s assume that a particular population of these dogs is inHardy-Weinberg equilibrium. The allele frequencies for our fouralleles are:
cch = 0.37
cd = 0.23
cb = 0.25
c = 0.15
a.   What is thefrequency of the cchcch,cbc, and cc genotypes in thispopulation?
b.   Among a populationof 2000 dogs, how many would you expect to have the pale grayphenotype, yet be heterozygous?
c.    Among apopulation of 5000 dogs, how many would you expect to have thewhite coat with dark eyes phenotype, yet be heterozygous?
d. Among a population of 15,000 dogs, how many would you expectto have cchcbor ccgenotypes?
