Chromosome banding

Chromosome banding
The treatment of chromosomes to reveal characteristic patterns of horizontal bands like bar codes. The banding patterns lend each chromosome a distinctive appearance so the 22 pairs of human nonsex chromosomes and the X and Y chromosomes can be identified and distinguished without ambiguity. Banding also permits the recognition of chromosome deletions (lost segments), chromosome duplications (surplus segments) and other types of structural rearrangements of chromosomes.

the use of various physical and cytochemical preparations with differential staining techniques, which allows visualization of differentially stained regions of a chromosome as a continuous series of light and dark bands specific for the chromosome and species; this has permitted definitive identification and delineation of all the chromosomes and chromosomal segments of many different species. Named according to the staining technique used, see C b., G b., Q b., and R b.
