Predation results in selection for more drab color patterns in guppies. Researchers further hypothesized that if predation pressure is reduced, drab coloration would become less beneficial (since females prefer brightly colored mates).
How did the types of data the researchers collected enable them to test their prediction?How did the types of data the researchers collected enable them to test their prediction? Tracking the number and area of colored spots provided a quantitative way to compare the brightness of different populations.
Why did dark colored rock pocket mice first appear in the population of light colored rock pocket mice?Why did dark-colored rock pocket mice first appear in a population of light-colored rock pocket mice? They have a genetic mutation that affects their fur color. There is dark lava rock in the area where they live. Individuals change color to blend in with the environment.
Do female guppies prefer to mate with males with bright color patterns or drab colors?Male guppies have highly varied color patterns, which are controlled by genes that are only expressed in adult males. Female guppies choose males with bright color patterns as mates more often than they choose males with drab coloring.
