Eye color genetics, computer artwork

Description: Eye color genetics. Computer artwork depicting the genetics of eye color. The color of the iris of the eye depends on the amount of melanin contained within its cells. If a lot of melanin is present, the iris is brown in color. However, if little melanin is present, the iris appears blue due to scattering of light by collagen fibers. At least three genes are known to influence eye color in humans by controlling the amount of melanin present. Genes are located on chromosomes (center left). Different versions of genes are known as alleles. The allele for brown eyes is dominant over the allele for blue eyes.
