Schematic band splitting of any chromosome; chromosomes are shown at same size in all stages; even though they would become larger the more bands show up. At the beginning, in extremely short chromosomes, there are no bands ('0'-band stage); at 350 band-level there are a few new Giemsa light bands (white), at 500 band-level additional Giemsa light bands appear (light gray) and the initial Giemsa light bands do not further split (white) – the same happens at 850- and 1600 band-levels – new Giemsa light bands develop from Giemsa dark bands – new Giemsa light bands are depicted in gray and dark gray.
