Abstract The constitutive heterochromatin, as demonstrated by the C band technique, may be subdivided into a number of categories when other characteristics are considered. The responses to fluorochromes QM and 33258 Hoechst, the behavior following G band staining, the repetitive DNA content, and many other criteria are useful for the classification of heterochromatin. The heterochromatin patterns of three mammalian species are presented to demonstrate that within each karyotype there may be several different types of C bands. In general, a correlation may also be made between GC-rich satellite DNA and dull (or negative) Q fluorescence, and between AT-rich satellite DNA and bright Q, fluorescence.
