A process by which one of the extreme variations of a trait is favored.

What is directional selection?

A population tends to evolve toward one end of a trait range due to a natural process called directional selection. Some characteristics, like eye color, are discrete and have distinct variations, but other characteristics are continuous and have a large range of almost infinite values (think height). Only one variety will be chosen for a specific attribute under directed selection (only blue eyes).

The highest or lowest value of a continuous feature will be chosen if a directional selection is applied (only tall people). When a population is subjected to directional selection over time, the qualities that are selected for will remain stable while the traits that are selected against will disappear.
