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?

a. directional
b. disruptive
c. stabilizing
d. normal

The correct answer is- B. disruptive

Explanation:

Disruptive selection or diversifying selection is the type of selection in which individuals who have extreme traits are selected over the individuals who are having the intermediate traits.

For example, dark and light-colored oysters have advantages of camouflage over medium colored oysters because white-colored oysters camouflage behind white stones and dark colors in shadows but medium color oyster have the limited region to camouflage from predators, therefore, their numbers are very low than the two extreme relatives.

So here also most of the worms are either short or long which shows that disruptive distribution is displayed in the population.
