Question

In a population with frequencies f(A)= 0.4 and f(a) = 0.6 at generation 0; what are the genotypic
frequencies before and after one generation of selection against the recessive phenotype given that
s= 20%. What are the gene frequencies after one generation of selection? What is the change in gene
frequencies for alleles A and a.
