Answer 1

It favors extremes in traits.

Step-by-step explanation:

3 types of selection:

• disruptive selection -- favors the extremes, leads to 2 distinct groups (ex. rocky environment -- gray and Himalayan rabbits are better able to blend in than white rabbits)
• directional selection -- favors one trait over all others, one trait's fitness increases (ex. peppered moths: black moths can remain better camouflaged from predators than white moths)
• stabilizing selection -- favors the intermediate (ex. birth weight: not ideal to be too light or heavy)
