Question

Through PCR, we have determined the PER3 genotypes for a class of students as follows:

H4/H4 = 125 individuals; H4/H5 = 90 individuals and H5/H5=85 individuals.

Using the genotype frequencies derived assuming that the class were a population in Hardy-Weinberg equilibrium, calculate the number of H4/H4 individuals that would be expected in the class (rounded numbers). Select only one answer.

1.96

2.129

3.171

4.42

5.147

6.57

7.72

Answer 1

Choice 6. (57)

This is an equivalent estimation of 0.645, the frequency of H4/H4 in the total population of 300 individuals.
