Question

which type of selection is shown in the graph?
o directional selection
disruptive selection
o stabilizing selection
number of butterflies
color of butterflies

Explanation:

Directional selection favors one extreme phenotype. In the graph, as the color of butterflies (phenotype) changes, the number of butterflies (population) shows a trend towards one extreme (indicated by the curve's direction). Stabilizing selection favors the intermediate phenotype (not shown here as no peak in the middle). Disruptive selection favors two extreme phenotypes (not depicted as there's no split into two high - number extremes).

Answer:

directional selection
