Adult male guppies use brightly colored patches to attract female mates. juvenile guppies are colorless. the original predator in the trinidad guppy experiment was the pike-cichlid, which feeds only on adult guppies. populations with no pike-cichlid predators had more brightly colored adults than populations that lived with the pike-cichlid. the killifish is another predator that feeds on guppies, but it only feeds on juveniles. a population of guppies is taken from a pond with pike-cichlids and placed in a pond with killifish. what will happen to the coloration in this population?
