Figure 1. Classical cytogenetic characterization ofAbracris flavolineata chromosomal complement at mitotic metaphase (a,d) and metaphase I (b,c,e–g) cells.

(a–c) conventional staining, (d,e) C-banding and (f,g) CMA₃ fluorochrome staining in cells with one or two B chromosomes. Insets show the B element obtained from another mitotic metaphase (a), and B chromosomes stained with DAPI (f,g). The B and X chromosomes are indicated in all cells, and (f) chromosomes with CMA₃-positive blocks are also indicated. The metaphases (e,g) are partial. Bar = 5 µm.
