Over many generations, certain insect species have become more and more resistant to insecticides. What type of natural selection does this show and how does it differ from the other types?
Caroline M.
Over many generations, why have certain insect species become more resistant to insecticides? 1. Disruptive selection has allowed only the extreme phenotypes to survive. 2. Only advantageous phenotypes have been able to reproduce. 3. Genetically unique new species have emerged from exposure to the chemicals. 4. Stabilizing selection has allowed only the intermediate insects to survive.

Which evolutionary process is shown in this picture? Following generations. Survivors. Pesticide application occurs. Resistant individuals survive and reproduce. More applications of pesticide will be less effective. The percentage of resistant insects grows.
