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.
NOTE: The Human Genome Landmarks poster is for educational purposes only, and is not intended to provide medical advice. Genes associated with the disorders and other traits listed on this poster were selected from the comprehensive database Online Mendelian Inheritance in Man(OMIM), which designated the status of each of these as confirmed or provisional as of July 2000. The extent of knowledge about any specific gene or disorder varies widely.

Human Genome Project 1990–2003
The Human Genome Project (HGP) was an international 13-year effort, 1990 to 2003. Primary goals were to discover the complete set of human genes and make them accessible for further biological study, and determine the complete sequence of DNA bases in the human genome. See Timeline for more HGP history.
Published from 1989 until 2002, this newsletter facilitated HGP communication, helped prevent duplication of research effort, and informed persons interested in genome research.
