Whole human karyotype depicted by ideograms starting at 350 band level going via 500 up to 850 bands. Each chromosome was analyzed by multicolor banding with special regard to the splitting up of chromosomal bands into sub-bands. Black numbers are in concordance with ISCN 2005, white had to be altered to show the biological correct way of band splitting. Only G-dark bands split into additional sub-bands. This context is exemplified in a biological nomenclature proposal, which starts with the names of the bands given in ISCN 2005 at the 300 band level (see also Table 1). The white and gray colorings of the GTG-light bands correspond to the splitting of the bands as explained in the legend of Fig. 2.
