2. Most male crickets produce a mating song by rubbing together their curved

wings. In a certain geographic area, parasitic flies detected male crickets singing

and deposited their larvae into them, which killed the crickets. Eighteen

generations later, the number of males with flat wings has increased to 90%. The

flat-winged crickets do not sing, but are still able to mate with females, and

parasitic flies cannot detect them. Which type of selection is occurring in this

cricket population?
