Question

In peppered, moth populations, light and dark moss are selected for in different environments which type of selection is this and what would a distribution curve for all peppered Moss look like

A disruptive selection two peaks at the extremes of the graph with a dip in the middle
B disruptive selection, a tall, narrow peak in the center of the graph
C stabilizing selection, a tall, narrow peak in the center of the
D stabilizing selection two peaks at the extremes of the graph with a dip in the middle

Answer 1

A disruptive selection is occurring in this scenario. The distribution curve for all peppered moss would have two peaks at the extremes of the graph with a dip in the middle. So the correct answer is D: disruptive selection, two peaks at the extremes of the graph with a dip in the middle. This is because the light and dark moss are being favored in different environments, leading to the persistence of both variations in the population and a decrease in the frequency of the intermediate phenotype.
