Human Genome Landmarks Poster: Chromosome Viewer

The Human Genome Landmarks poster is a 24" by 36" wall poster that lists selected genes, traits, and disorders associated with each of the 24 different human chromosomes. Download PDF

Each chromosome on the wall poster can be viewed online or downloaded from our chromosome image gallery.

The chromosome viewer below is another way to see each chromosome on the poster. Select a chromosome to view it online or print it.

The guides and tutorials at Gene Gateway supplement this poster by helping you find and use databases and other resources for learning more about the genes, traits, and genetic disorders associated with each chromosome.

The Human Genome Landmarks poster and Gene Gateway are products of the Biological and Environmental Research Information System of the U.S. Department of Energy Office of Science.

Magenta and green. These regions reflect the unique patterns of light and dark bands seen on human chromosomes that have been stained to allow viewing through a light microscope.

Red. The centromere, or constricted portion, of each chromosome.

Yellow. Chromosomal regions that vary in staining intensity and are sometimes called heterochromatin (meaning "different color").

Yellow with thin magenta horizontal lines. (e.g., on chromosome 21) denote variable regions, called stalks, that connect a very small chromosome arm (a "satellite") to the chromosome.
