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)

Question

stabilizing selection; two peaks at the extremes of the graph with a dip in the middle
O stabilizing selection; a tall, narrow peak in the center of the graph
• disruptive selection; two peaks at the extremes of the graph with a dip in the middle
disruptive selection; a tall, narrow peak in the center of the graph

Answer 1

The correct answer is: disruptive selection; two peaks at the extremes of the graph with a dip in the middle.

In disruptive selection, individuals at both extremes of a trait (in this case, light and dark peppered moths) are favored, resulting in a distribution curve with two peaks (one for light moths and one for dark moths), and a dip in the middle where the intermediate (medium-colored) moths are less fit in those environments.
