Summary
A scanning electron microscope study of bristle mutations inDrosophila melanogaster has shown that the cell hairs (trichomes) can be altered in predictable ways. The trichomes appear to act as markers of a diffusion gradient dttermining the orientation of cuticular structures in the thorax.
