Chromosome inversion, paracentric
The chart of the linear array of genes on a chromosome.
A chromosome map can also refer to the visual appearance of a chromosome when stained and examined under a microscope.
Particularly important are visually distinct regions, called light and dark bands, which give each of the chromosomes a unique appearance.
This feature allows a person's chromosomes to be studied in a clinical test known as a karyotype, which allows scientists to look for chromosomal alterations.
