Drosophila melanogaster’s ability to perceive and differentiate color was studied. The flies were introduced into a maze with the color choices of red, blue, green, and yellow. We have improved the apparatus of previous in order to increase the amount of flies obtained during each test. After the initial test was done, flies showing a preference to a certain color were assessed for the color preference a second time. Those showing color preference after two tests were then bred with each other in an effort to select for a genetic predisposition for that particular color, in other words the second generation flies where then tested to find whether color differentiation was hereditary. Our results show Drosophila melanogaster have color perception abilities. Further results will be presented.
