Which of these best describes directional selection? One phenotypic extreme is favored, pushing the distribution towards that phenotype Middle phenotype is favored, pushing the distribution towards that phenotype Both phenotypic extremes are favored, pushing the distribution towards those phenotypes and decreasing phenotypes from the center of distribution

Both extremes of an array of phenotypes are favored. Stabilizing selection. One extreme of an array of phenotypes is favored. Directional selection. guppies with killifish guppies with pike cichlids and killifish. Small, drap, early reproduction is favored. The midrange of an array of phenotypes is favored. Disruptive selection. Large, colorful, later reproduction is favored.
