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:

Disruptive distribution (also called diversifying selection) is characterized by most individuals in a population having extreme traits (either short or long in this case), with fewer individuals having intermediate traits. Directional distribution favors one extreme, stabilizing favors the intermediate, and normal is a bell curve with most individuals at the mean. Since most worms are either short or long, the distribution is disruptive.

Answer:

B. disruptive
