Question

carlos is collecting data about the length of earthworms in his backyard. the shortest worm he found is 4 inches long; the longest worm is 8 inches long. if most of the worms are either short or long, which type of distribution is displayed in the population?

directional
disruptive
stabilizing
normal

Explanation:

In disruptive selection, extreme phenotypes are favored over intermediate ones. Here, most earth - worms are either short or long (extreme phenotypes), not of intermediate lengths. Directional selection favors one extreme, stabilizing selection favors the intermediate, and normal distribution has a bell - shaped curve with most values around the mean.
