Diagrams of heterochromatic blocks of chromosomes 2 and 3 and the positions of the genes located in the pericentric heterochromatin. The position of the centromere is indicated by a constriction and the letter C. The blocks are numbered as in Figure 2. The position of the genes is shown by bars below the block diagrams and the list of the genes below the bars. The brightly fluorescing blocks are black, less bright in gray and dull regions in white.
