Question

which form of natural selection does the graph represent?
proportion of individuals
trait value
original population
population after selection
directional selection
disruptive selection
sexual selection
stabilizing selection

Explanation:

Disruptive selection favors extreme phenotypes over intermediate ones. In the graph, the original population (orange) has a single - peak distribution for a trait value. After selection (purple), the population splits into two distinct peaks at the extremes of the trait value, indicating that extreme forms of the trait are being selected for while intermediate forms are being selected against.

Answer:

B. disruptive selection
