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?

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?

a. stabilizing selection; two peaks at the extremes of the graph with a dip in the middle
b. disruptive selection; two peaks at the extremes of the graph with a dip in the middle
c. distribution selection; a tall, narrow peak in the center of the graph
d. stabilizing selection; a tall, narrow peak in the center of the graph

Answer 1

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

This is because in peppered moth populations, light and dark moths are selected for in different environments, leading to two distinct peaks in the distribution curve with a dip in the middle.
