In a beetle population the initial allele frequencies are p = 0.6 for allele A and q = 0.4 for allele a. The relative fitnesses are w_{AA}=0.9, w_{Aa}=1.0 and w_{aa}=0.7. After one generation of selection, what is the new frequency of allele A? Also state the change in heterozygosity (2pq) caused by this selection (give the numerical difference, to three decimal places).

Answer Options

A. p' ≈ 0.600; heterozygosity change = 0.000
B. p' ≈ 0.630; heterozygosity change = -0.002
Correct Answer C. p' ≈ 0.616; heterozygosity change = -0.006
D. p' ≈ 0.590; heterozygosity change = -0.010
Correct Answer
C
Correct Option:
p' ≈ 0.616; heterozygosity change = -0.006
