Scanning electron micrograph of the fruit fly Drosophila melanogaster. The specimen is a White Miniature Fork mutant. Drosophila is chosen as the subject of genetic experiments,particularly on mutation,because it is easy to raise in large numbers & reproduces rapidly. Mutations shown here include wing size & shape,& the formation of the bristles. The wings on a normal fly are longer,extending beyond the end of the body,& fold over the abdomen when at rest. The bristles (setae) on the body are shorter in the mutant & many are distorted,either curled or forked. This mutant also has white compound eyes,whereas the wild fly has red ones.
