Question 7 • TPS EdX Biology

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?

Answer
A
normal
B
stabilizing
C
disruptive
D
directional

Explanation

A disruptive distribution favors individuals at both extremes—in this case, the shorter and longer worms—rather than those with an average length. Since most worms are described as either short or long, the population displays a disruptive distribution. A normal distribution would have most worms near the middle length.
