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:

• Stabilizing selection: Favors intermediate - sized organisms, reducing diversity by selecting against extreme phenotypes.
• Directional selection: Shifts the population towards one extreme phenotype (e.g., larger organisms in this case).
• Disruptive selection: Favors both extreme phenotypes, increasing diversity.
• Adaptive selection is a general term and not one of the three main types of natural selection (stabilizing, directional, disruptive) described in population genetics.

Answer:

B. directional selection
