Male guppies that have colorful spots on them are chosen more often by female guppies for mating. Males can have from one to six spots. The more spots they have the more females are attracted to them. However, bright spots also make the males more
vulnerable to predators. In a pond with predators, male guppies have an average of 3.2 spots. Predict what would happen to the average spot number on the males over the generations if you removed all predators from the pond. Using natural selection, explain your answer.
