Blue is definitely dominant over green, but brown is dominant over both.What eye color is more dominant: blue or green?
There are dominant and reccessive genes in each parent, but aparantly because there are so many possible eye colours its hard to draw a genetic cross over diagram for eye colour..
Thus , eye color is a polygenic trait. The variations in color in the eye are caused by ratios of eumelanin (produced by melanocytes) in the iris. The melanin content of the iris epithelium, the melanin content within the stroma, and the cellular density of the iris contribute to the color of the iris.
It is hard to determine how to predict eye color. I believe there are three loci that are associated with eye color (brown, green, and blue) and any mixture of these will produce hazel, and to result in a pure color, all four gene must read the same loci.
Blue eyes are really the only color that is genetically linked.(recessive) So , green is more dominant than blue . However, brown is the most dominat over both.
