Fruit Fly Imaginal Disc - Wing
Featured above is composite series of images of a Drosophila (fruit fly) wing imaginal disc. Different color combinations of this double-labeled sample reveal the location of wingless genetic mutants: achaete genes in red/yellow, yellow/white, purple/white, or blue/white and apterous genes in green, blue, green, and red, respectively.
In fruit flies, imaginal discs are the developmental tissues from which many adult structures, including eyes, wings, and halteres, are formed.
