What is the expected frequency of the a2a2 genotype?

To calculate the expected frequency of the a2a2 genotype, we need to use the Hardy-Weinberg equation. According to the Hardy-Weinberg principle, in a population in genetic equilibrium, the genotype frequencies can be calculated using the allele frequencies.

The formula to calculate the genotype frequency of the a2a2 genotype is as follows:

f(a2a2) = (p(a2))^2

Where:

  • f(a2a2) represents the frequency of the a2a2 genotype
  • p(a2) represents the frequency of the a2 allele

Given that the frequency of the a2 allele is 0.65, we can substitute this value into the formula:

f(a2a2) = (0.65)^2
f(a2a2) = 0.4225

Therefore, the expected frequency of the a2a2 genotype in this population is 0.4225 or 42.25% when rounded to two decimal places.
