Eye color. Eye color is a polygenic phenotypic trait determined by two factors: the pigmentation of the eye 's iris [ 1][ 2] and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris. [ 3]: 9. In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of ...
To some extent, skin color is determined independently of eye and hair color, as can be seen from variation in skin coloration in human populations. For the evolution of human skin color, see section above. [37] [52] [53] [47] [54] [55] For skin color, heritability is very high, even though it can be modified by exposure to sunlight.
Heterochromia iridum. Heterochromia is a variation in coloration most often used to describe color differences of the iris, but can also be applied to color variation of hair [1] or skin. Heterochromia is determined by the production, delivery, and concentration of melanin (a pigment ). It may be inherited, or caused by genetic mosaicism ...
Dark skin. Dark skin is a type of human skin color that is rich in melanin pigments. [1] [2] [3] People with dark skin are often referred to as black people, [4] although this usage can be ambiguous in some countries where it is also used to specifically refer to different ethnic groups or populations. [5] [6] [7] [8]
Periorbital hyperpigmentation. Periorbital hyperpigmentation, also known as hereditary dark circles, is characterized by darker skin around the eyes caused by the presence of additional melanin. It is an extremely common hereditary human characteristic and is frequently found on individuals with dark skin. Periorbital hyperpigmentation is most ...
