The SECOND graph represents selection that may lead to reduced variation. It is an example of stabilizing selection.
<h3>What is Stabilizing selection? </h3>
Stabilizing selection is a type of natural selection that leads to a decrease in the genetic variation of the population.
In Stabilizing selection, natural selection tends to favor an average phenotype and then can remove (select) extreme variations.
Stabilizing selection generates a modified bell curve graph in which the central portion is narrower and it is taller than the normal distribution bell shape.
