Question
The following graph shows which type of natural selection?
- Stabilizing selection
- Disruptive selection
- Directional selection
- Genetic drift
Hint:
The graph shows stabilizing selection.
The correct answer is: Stabilizing selection
- Stabilizing selection is also referred to as "middle-of-the-road" selection since it favors a non-extreme characteristic over one of the two extreme ones.
- Plant height is an illustration of this.
- Short plants may not receive enough sunlight in a population of plants, and towering plants may sustain wind damage.
- Which reduces the number of very tall and very short plants and increases of medium-height plants.
- This selection is thought to be the most prevalent method of natural selection because most features do not change significantly over time.
