A) directional selection to insecticide resistance in the insects.

Question

Quizplus · Accepted Answer

The use of DDT selected for mosquitoes that had genetic mutations conferring resistance to the insecticide, leading to directional selection. This means that the allele frequencies in the mosquito population shifted in favor of those alleles that provided resistance to DDT, allowing those individuals to survive and reproduce more than those without resistance.
