Question

In peppered moth populations light brown moths are selected

Answer 1

against and dark brown moths are selected for. This is due to the prevalence of pollution in industrial areas, where dark brown moths are able to camouflage themselves better against the soot-covered trees and thus have a higher survival rate. Light brown moths, on the other hand, are more easily spotted by predators in these polluted areas and have a lower survival rate. Over time, this selective pressure has led to an increase in the population of dark brown moths and a decrease in the population of light brown moths in industrial areas.
