The same species of guppy (a fish) lives in two different ponds. In pond A, there is a species of pike (also a type of
fish) that eats the guppies, the smaller, browner guppies in this pond survive because they aren't eaten. In pond B,
dragonfly larvae eat the smallest guppies, so only large guppies survive. After many generations, all the guppies in
pond A are small and brown, while all the guppies in pond B are big and colorful. Which population of guppies has a
higher fitness? Is either population of guppy more fit than the other? Explain your answer.

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
