Macrophotograph of a normal & a mutant fruit fly pupa of the species Drosophila melanogaster. Each pupa is encased in a hard,barrel-shaped puparium with breathing tubes,or spiracles,at each end. The pupa on the right,with red compound eyes,is the natural,or wild type,known as Oregon R. The pupa on the left is a mutant known as White Miniature Forked. It has white eyes,shorter wings than the normal fly,& the bristles on its face & body are distorted & forked. Drosophila is used in genetic studies because it is easy to raise in large numbers,reproduces rapidly,& its mutations are easy to identify | |
