eye colour

[snow_storm]

why are green eyes rarer than blue and brown eyes? I know it's something to do with genetics but i'm not quite sure about the details.

to conceive a green-eyed baby the parents must have sex on green linens or a green lawn. not many people know this secret. well now it's exposed.

I dont think green eyes are all that rare, I have green eyes and I know quite a few people with green eyes. some people have dark green eyes that can be mistaken for browns/hazels and greys!

They aren't classed as rare, just less common than the other colours. They are rare in african/asian people. Hth.

Eye colour is a polygenic trait - meaning that it is controlled by the interactions of several genes. Rare genetic mutations can even lead to unusual eye colours like black, red, and violet. Often, paler newborns have blue eyes, which change to green, hazel, light brown or dark brown. It is thought that exposure to light after birth triggers the production of melanin in the iris of the eye. By three years of age, the eyes produce and store enough melanin to indicate their natural shade.

Green eyes are the product of moderate amounts of melanin. Only 1-2% of the world population have Green eyes. They are most often found among people of Northern and Southern European origin. Countries with a high percentage of green eyes are Iceland, Sweden, Denmark, Finland, Norway, Germany, Ireland and the Netherlands. Green eyes are also present in Eastern and Southern Europe and in the Middle East.

In humans, brown eyes contain large amounts of melanin (eumelanin) within the iris stroma, which serves to absorb light, particularly at the shorter wavelengths. Brown is the most common eye colour but less common in countries around the Baltic Sea, such as Finland and Estonia.

I have green eyes and no one in my family does. I also only know one person with green eyes. I did find Octo's answer informative I didnt realise so little people had green eyes.

My Mum's eyes were grey. My Dad's eyes are a pale green. Mine are so green, they make people recoil in a certain light.
