disruptive selection; two peaks at the extremes of the graph with a dip in the middle

In peppered moth populations, light and dark moths are selected for in different environments, leading to an increase in the frequencies of both light and dark moths, with a decrease in the number of intermediate, or gray, moths. This is an example of disruptive selection, where individuals with extreme phenotypes are favored over intermediates. The distribution curve for all peppered moths would show two distinct peaks at the extremes (light and dark moths) with a dip in the middle (gray moths).
