Caption: Light micrograph in Rheinberg illumination of giant polytene chromosomes of Drosophila funebris. These chromosomes are found in the salivary glands of D.funebris and many other fly species. The giant structure occurs when succesive replicate strands of chromosome substance fail to separate from one another, instead lining up precisely. With careful microscopy, the minute structure of the chromosomes may be studied. Magnification x400 at 35mm size.
