Normal and mutated fruit fly heads. Coloured scanning electron micrograph (SEM) of the heads of a normal (left) and a mutated (right) fruit fly (Drosophila sp.). The difference between the two is most obvious in their compound eyes (red). The mutant's eyes are smaller and more irregular than those of the normal fly. Mutations such as this are created by genetic researchers studying the effects of altering the flies' DNA (deoxyribonucleic acid),the chemical which carries the genetic code. Drosophila sp. is widely used for genetic experiments because it reproduces rapidly and is easily manipulated in the laboratory. Magnification unknown | |
