2.Guppies are small fish that live in fresh

water. Most guppy species reproduce sexually, but some reproduce asexually. There are two lakes

in a particular region. One lake contains a species of guppy that reproduces asexually. The

other lake contains a species of guppy that

reproduces sexually. A scientist studying these lakes predicts that the sexually reproducing

guppies would survive better than the asexually reproducing guppies if a fungus was introduced to

both lakes. Which statement supports this hypothesis?
