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:

The original population has a single peak (average trait values are most common). After selection, the population has two peaks, meaning extreme trait values are favored while average trait values are selected against. This matches the pattern of disruptive selection. Directional selection shifts the peak to one extreme, stabilizing selection narrows the peak around the average, and sexual selection relates to mating traits not this trait distribution shift.

Answer:

disruptive selection
