False-colour scanning electron micrograph of a mutant fruit fly,Drosophila melanogaster,with four wings. The normal fly has one pair of wings. Drosophila melanogaster has been used for many years in genetic research because it is easy to raise in large numbers in the laboratory,reproduces rapidly,and many of its mutations are easy to see under a low-powered microscope. Adult flies are 2-3mm long. Among the structures of the fly which are affected by mutations are the length of wings,eye colour and body bristles. An entirely new pair of wings is unusual. Drosophila is probably the animal which has contributed most to genetic studies. Magnification: x6.5 at 35mm size | |
