Giant Polytene Chromosomes in Hypodermal Cells of Developing Footpads of Dipteran Pupae

Large hypodermal cells with giant polytene chromosomes are present within the developing feet of Sarcophaga and other fly pupae. The cells secrete a large volume of cuticle; at this time there is extensive "puffing" of the chromosomes. Being hypodermal and superficially situated with permanent secretory products, the cells could be ideal experimental and genetical tools.
