Question

18 multiple choice 1 point in a marine population, male guppies show highly variable patterns of colorful spots. the fish may either have small spots that help them blend with the surroundings or large, bright spots that increase the chances of being located by female fish. which change would most likely eliminate the trait of large, bright spots in male guppies? increased space for nesting increased competition for mating lack of sufficient food presence of many predatory fish clear my selection previous next

Explanation:

Large, bright spots make male guppies more visible. In the presence of many predatory fish, guppies with such spots are more likely to be eaten. This selective pressure would likely eliminate the trait over time. Increased space for nesting, increased competition for mating, and lack of sufficient food do not directly target the survival - disadvantage of the bright - spot trait as predators do.

Answer:

D. presence of many predatory fish
