If this population is subject to stabilizing selection for several generations, which of the distribution is most likely to result?
Options:
Answer:
A
Solution:
Stabilizing selection is a type of natural selection that favors the average individuals in a population. This process selects against the extreme phenotypes and instead favors the majority of the population that is well adapted to the environment. Stabilizing selection is often shown on a graph as a modified bell curve that is narrower and taller than the norm.
