Eye color is a polygenic phenotypic trait determined by two factors: the pigmentation of the eye's iris and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris.

23 ago 2021 · Introduction. Eye colour, or more correctly iris colour, is often used as an example for teaching Mendelian genetics, with brown being dominant and blue being recessive. Colour blindness “Daltonism”, which affects 8% of the male population, is a leading example for teaching X-linked recessive disease (Fig. 1 ).

22 feb 2024 · At least 16 different genes influence eye color. Your genes control how much melanin pigmentation your iris produces—the thin, circular structure in your eye that gives it its color. Hazel eyes are a dominant trait. A single copy of the gene for hazel eyes is enough to make your eye color this shade.
25 apr 2024 · eye colour, heritable phenotypic (observable) trait determined by pigmentation and light scattering in the iris of the eye. The iris, the coloured part of the eye, is the ring of muscle and collagen fibres around the central black opening of the eye known as the pupil, through which light passes.
11 mar 2024 · What gives my eyes their color? Your eye color refers to the color of each eye’s iris, a double-layered ring of muscle tissue around your pupil that controls how much light enters your eyes. The color of your iris depends on a few different factors between it and other parts of your eye.
An organism's "eye color" is actually the color of one's iris, the cornea being transparent and the white sclera entirely outside the area of interest. Melanin is yellowish to dark hazel in the stromal pigment cells, and black in the iris pigment epithelium, which lies in a thin but very opaque layer across the back of the iris.
