Quizplus · Accepted Answer

The figure shows that the insect population is experiencing selective pressure due to the insecticide spray. The insects that are most resistant to the insecticide will survive and pass on their resistant traits to their offspring, leading to an increase in the frequency of these traits in the population. This is an example of natural selection, which is the process by which certain traits become more or less common in a population over time due to their effects on survival and reproduction. Genetic drift, founder effect, and gene flow do not accurately describe the process shown in the figure.
