Step-by-step explanation:

Directional selection is changing genotypes in a particular direction.

Answer 2

Under the directional selection, the genotype might change and the genotypes is the one that represent larger individuals become more prevalent. It might change, the Genotype frequencies under directional selection that the Genotypes that represent larger individuals become more prevalent. The answer in this question is the genotypes is the one that represent larger individuals become more prevalent.
