A researcher records the eye colour of one hundred test subjects. this type of data can be classified as nominal.
Two different elements, namely the colour of the eye's iris and the frequency-dependence of light scattering by the turbid medium in the stroma of the iris, influence the eye's colour, which is a polygenic phenotypic trait. The amount of melanin present in the iris pigment epithelium determines the colour of the iris in human eyes, which ranges from light brown to black. Thus, eye colour is a structural colour that changes based on illumination, especially for lighter-coloured eyes. Human eye colour is complicated by genetics and heredity. As many as 15 genes have been linked to the inheritance of eye colour thus far. Almost any parent-child combination of eye colours can occur due to the complexity of the genetics governing eye colour.
