Which of the following is an example of directional selection?
Answer The increase in antibiotic-resistant strains of bacteria.
In directional selection individuals towards one end of the distribution of a character have greater reproductive success than individuals who are further away from that end of the distribution. For example, if people of less than average height left more offspring than those of average or greater than average height, then, through time, average height would become smaller (move in the direction of a lower height).
