Step 1: Male guppies located below South American waterfalls where predation is high tend to exhibit drab coloration to blend in with their surroundings and avoid attracting predators. Show more…

Guppies exhibit sexual dimorphism in some pools due to intersexual selection, but the frequency of brightly colored males in a population varies depending on environmental factors such as the presence or absence of predators in the pool. Which of the following would you expect to occur in a captive population of guppies collected from Trinidad if you allowed them to breed for many generations in an aquarium WITHOUT predators? Female guppies will become more brightly colored. Male guppies that are brightly colored will have better reproductive success than dull males. The number of dull-colored male guppies will eventually equal the number of brightly colored males. Female guppies will prefer to mate with the dull-colored males.

Female guppies prefer to mate with more colorful males; thus, male guppies have become quite colorful over time. Which factor is most likely to cause male guppies to evolve duller colors over time? A) availability of food B) number of offspring C) predator behavior D) water temperature

Female guppies exhibit two different reproductive strategies depending on environmental conditions. Strategy A: female guppies mate with a male guppy and produce offspring that inherit 50% of her genes Strategy B: female guppies do not mate with a male guppy, but produce offspring that inherit 100% of her genes a) This strategy represents the ancestral state in terms of reproduction: b) This strategy will give the female higher fitness if there are many parasites around: c) This strategy will probably give the female higher fitness if the environment is stable (not changing): d) This strategy allows the female to remove deleterious mutations from her lineage: e) This strategy results in offspring with greater genetic diversity:
