What would be the frequency of pink flowers in a population where the allele frequency of C^R is 0.4 and the population is in Hardy-Weinberg equilibrium? Assume that C^R C^R is red,C^RC^W is pink,and C^wC^w is white. A)0.04 or 4% B)0.16 or 16% C)0.2 or 20% D)0.8 or 80% E)0.48 or 48%

In a population in Hardy-Weinberg equilibrium, the frequency of genotypes can be calculated using the equation p^2 + 2pq + q^2 = 1, where p and q represent the frequencies of two alleles, and 2pq represents the frequency of the heterozygous genotype. Given that the allele frequency of C^R is 0.4 (p = 0.4), the frequency of the other allele (q) would be 0.6 (since p + q = 1). The frequency of pink flowers, which are heterozygous (C^RC^W), would be represented by 2pq. Therefore, 2pq = 2 * 0.4 * 0.6 = 0.48 or 48%.
