Different Colored Eyes Genetics

It’s what Dalton says about the genetics of color vision. He wasn’t the first person to suggest that the human eye had three receptors for different colors, but he was the one who made the most.

Color is perceived by light hitting clusters of cells called cones in the back of the eye. Different cones pick up different wavelengths. When these cones don’t work properly, usually for genetic.

Heterochromia iridum. The affected eye may be hyperpigmented (hyperchromic) or hypopigmented (hypochromic). In humans, an increase of melanin production in the eyes indicates hyperplasia of the iris tissues, whereas a lack of melanin indicates hypoplasia. The term is from ancient Greek: ἕτερος, héteros meaning different and χρώμα, chróma meaning color.

Jan 26, 2014  · An unpigmented human eye is blue, due to the way the fibers in the iris react with light; the color varies in other species. If you have the gene to produce pigments, the eye will be various shades of brown, depending on exactly what pigment you are producing. The same gene covers pigmentation in both eyes.
