In a large population of randomly breeding individuals, the frequency of a recessive allele is initially 0.3. there is no migration and no selection. humans enter this ecosystem and selectively hunt individuals showing the dominant trait. when the gene frequency is reexamined at the end of the year,

The frequency of the homozygous dominants will go down, the frequency of the heterozygous genotype will go down, and the frequency of the homozygous recessives will go up. This is because the hunting by the humans reduces the population of individuals with the dominant trait and reduces their chances of reproduction and the passing of their genes to the subsequent generation.
