All of these types of selection can affect the distribution of a quantitative trait. Directional selection favors one extreme of the trait distribution, potentially shifting the entire distribution over time. Disruptive selection favors both extremes of the trait distribution, potentially leading to a bimodal distribution. Stabilizing selection favors the mean of the trait distribution, reducing variation and making the distribution more narrow.
