Abstract
PARTICULAR chromosome regions have been found to fluoresce intensely after staining with quinacrine and related compounds1–16, and we have been studying the pattern of distribution of these regions in the chromosomes of various species and laboratory stocks from the genus Drosophila. We find that these patterns vary in interesting ways and that they are a characteristic of chromosomes that can be used in studies of evolutionary cytogenetics in much the same way as structural rearrangements17–19. The following are among our observations.
