In many organisms, including guppies, females choose with whom they mate. This is called female selection. For our experiment male and female guppies have been isolated from each other and then we tested to see if females preferred similar looking males in a bright environment more than a male in a neutral colored environment. We hypothesized that the female would prefer the male in the brighter colored environment over the males in the neutral colored environment. We predicted that the female would touch the glass on the brighter side more frequently.
