What is the frequency of plants with red flowers homozygotes

What is the frequency of plants with red flowers (homozygotes for CRCR) in a population if the frequency of the CW allele is 0.32 and the population is in H-W equilibrium? Assume that CW and CR are the only 2 alleles for flower color.

A) 0.68

B) 0.44

C) 0.46

D) 0.57

Solution

A) 0.68

Given that the frequency of CW allele is = 0.32, and the population is in H-W equilibrium.

Thus, the frequency of CW + frequency of CR = 1

Frequency of CR = 1- 0.32 =0.68
