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

Responses

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

disruptive 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 the case of peppered moths, individuals with extreme phenotypes (light and dark coloration) are favored in different environments (light-colored trees vs. dark-colored soot-covered trees), leading to a distribution curve that has two peaks at the extremes, indicating that both light and dark moths are selected for.
