WebNatural Selection: Modes of Selection. There are three general modes of selection: Directional Selection occurs when selection favors one extreme trait value over the other extreme. This typically results in a change in the mean value of the trait under selection. Disruptive Selection occurs when selection favors the extreme trait values over ... WebNatural selection.
