If a population of monkeyflowers has 500 members with 135 of genotype DD, 280 of genotype Dd, and 85 of genotype dd, what is the frequency of the D allele?
A) 0.275
B) 0.415
C) 0.45
D) 0.55

The frequency of the D allele is calculated by taking the number of D alleles in the population and dividing by the total number of alleles. There are 135 DD individuals contributing 270 D alleles and 280 Dd individuals contributing 280 D alleles, totaling 550 D alleles. The total number of alleles is 1000 (500 individuals x 2 alleles each). Thus, the frequency of the D allele is 550/1000 = 0.55.
