  • Chromosome and list of related traits.

    Chromosome 19

    • 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. Denote variable regions, called stalks, that connect a very small chromosome arm (a “satellite”) to the chromosome.

  • Chromosome illustration and list of related genes.
