The Genetics of Hazel Eyes

Environmental colors and lightings alter the appearance of hazel eyes, thus it is difficult to define them. Just like for example, blue, green and hazel eyes are as deep as a pond in which the water appears to be blue if the sky is blue and appears to be gray or brown if the sky is overcast. Captured photographs can testify that without the benefit of the natural scattering of light, hazel eyes habitually appear brown or dark gray.

Hazel Eyes Heredity

Only a few of research studies tell about the heredity or genetics of hazel eye color. But a model studied by Dr. Barry Starr of Stanford University can explain about hazel eye color genetics. According to the him, a new gene which is yet to be found could be a modifier form of the gey gene which is named big (M) that can produce hazel eyes by having the gey that makes more melanin. As with any gene, the big (M) comes with two alleles, the big M which increases the amount of melanin gey makes and the little (m) which has no pigmentation effect.

Considering the possible mixtures of the G (gey) and the M (modifier) genes would be possible to explain hazel eyes theoretically. Anytime an individual get G with the M gene he will obtain hazel eyes. Thus, if a person has the following mixtures: GGMM, GbMM, GGMm, and GbMm he will have hazel eyes. If the person has GGmm or Gbmm he will own green eyes and if he has bbMM, bbMm, or bbmm he will have blue eyes.

Hazel eye genetics will come to clarity sooner. For a while, it’s the presentation of Dr. Starr that gives the public the best explanation so far.

Genetics likewise determines the human characteristics of blue eyes, blonde hair, and red hair.

Hazel Eye Uniqueness

Hazel eyes have a brown ring around the iris, and either green or blue coloring around the outside part of the ring. If you take a closer look, darker inner ring is bordered by a lighter outer ring.

Brown eyes have been known for dominance and green ones are least common. There is a diversity of colors and shades in between. Likewise, several strange eye colors like red and violet exist while brown, green and blue eye color comes from a pigment identified as melanin. Brown eyes have dominant melanin in the iris whereas green eyes have less, and blue eyes have diminutive or no pigment at all.

Indeed, hazel eye color is the most misread eye color of all due to the border of brown and green. Thus, it is a pretty indefinite description. But to be particular, hazel eyes can be called as a mixture of brown and green. Various tinctures of brown to dark golden and green are often found with these eyes. They are brown near the cornea and golden to green towards the outer sides of the eyeball. People with hazel characteristics are beautiful and gorgeous with one of the most captivating pair of eyes.[ad#afterpost]
