Selection for one extreme phenotype in a population would be considered _______ selection.Multiple choice question.directionalstabilizingbalancingdisruptive

Answering the Question

1. Break Down the Problem

   • Identify the type of selection being described in the question.

2. Relevant Concepts

   • In evolutionary biology, different modes of natural selection can be identified, such as:
     • Directional Selection: Favors one extreme phenotype.
     • Stabilizing Selection: Favors the intermediate phenotypes.
     • Balancing Selection: Maintains diversity by favoring multiple phenotypes.
     • Disruptive Selection: Favors extreme phenotypes at both ends of the spectrum.

3. Analysis and Detail

   • The question specifically states "one extreme phenotype," which corresponds to directional selection where that particular trait is advantageous, leading to its increase in frequency in the population over time.

4. Verify and Summarize

   • According to the definitions, if one extreme phenotype is favored, the selection is characterized as directional selection.

Final Answer

The answer is directional selection.
