In a large, isolated population of an insect species, a specific gene locus has one dominant allele (A) and one recessive allele (a). The genotype frequencies of the gene were collected for ten generations, as shown in Table 1. Table 1. Genotypic frequencies over ten generations in an insect species AA Aa aa Generation 1 0.47 0.43 0.10 Generation 5 0.32 0.60 0.08 Generation 10 0.20 0.75 0.05 Which of the following could best account for the change in genotypic frequencies over the ten generations?
