Which type of selection results in greater genetic variance in a population?
stabilizing selection
directional selection
diversifying selection
positive frequency-dependent selection

diversifying selection

Explanation:

Diversifying selection is one in which extremes are favored and intermediate organisms are eliminated. An example of this type of selection can be seen in some African finches that are adapted to eating seeds. They vary in size (large, medium and small), but intermediate forms are rarely observed.  This is because there are seeds that vary in hardness. Larger finches feed on hard seeds, and smaller finches feed on soft seeds. This type of selection results in large genetic variation in the population.  This is because there are seeds that vary in hardness. Larger finches feed on hard seeds, and smaller finches feed on soft seeds. This type of selection results in large genetic variation in the population.
