Abstract
The ultrastructure of polytene chromosomes of Drosophila and Stylonychia were compared in whole-mount spread preparations. In Drosophila the chromomeres appear as dense, unresolvable structures interconnected by 10-nm interband fibers. In contrast, chromomeres of Stylonychia polytene chromosomes are formed by aggregates of 30-nm loops laterally attached to 10-nm interband fibers. It is suggested that the polytene chromosomes in these two species are analogous rather than homologous structures.
