Guppies from Trinidad form two distinct populations that differ in several life history traits. These traits appear to relate to the local predator populations, pike-cichlids or killifish. Which experiments would best test the heritability of these

traits?

A) Raise both populations with cichlids to see if the population of smaller, faster-maturing guppies reproduces more quickly.
B) Raise both populations without predators to see if they maintain their life history traits.
C) Introduce cichlids into a habitat with killifish.
D) Provide additional food to the guppies from cichlid habitats to see if they will grow to the same size as guppies from the killifish habitat.
