Question

In peppered moth populations, light and dark moths are selected for in different environments. Which type of selection is this, and what would a distribution curve for all peppered moths look like?(1 point) pick one answer

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

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

stabilizing selection; a tall, narrow peak in the center of the graph

Answer 1

The correct response is:

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

In disruptive selection, individuals at both extremes (light and dark moths) are favored, leading to a distribution curve that has two peaks corresponding to those extreme phenotypes and a dip in the middle for the intermediate phenotypes.
