Question

which type of selection occurs when a population experiences a shift in diversity toward the larger organisms?
○ stabilizing selection
○ directional selection
○ disruptive selection
○ adaptive selection

Explanation:

To determine the type of selection, we analyze each option:

• Stabilizing selection favors intermediate phenotypes, reducing variation.
• Directional selection shifts the population's trait distribution toward one extreme (here, larger organisms).
• Disruptive selection favors two extreme phenotypes, increasing variation between them.
• Adaptive selection is not a standard type of natural selection (the main types are stabilizing, directional, disruptive).

Since the population shifts toward larger organisms (one extreme), directional selection is correct.

Answer:

B. directional selection
