A dog breed has a pair of alleles that determine curly hair (C) versus straight hair (c). Given allele frequencies of C = 0.1 and c = 0.9, solve the Hardy-Weinberg equation to determine the expected frequencies of individuals in the population having genotypes CC, Cc, and cc. Choose the correct value in each case.
