Eye Colour Genetics and Mutations

On the subject of Eye Colour, there's  a lot that people don't know. 

Now, I've done my research, and I've collected a heck of a lot info about Eye colour genetics and mutations. So I'm going to write down all I know.

What Colours Are Most Common?

You'l find that the people in Southern Countries, like Africa and Asia, have dark brown eyes, some may even appear black. and Northern countries most commonly have blue or green eyes. 

In fact, scientists have found that 99% of the population in Scandinavia have blue eyes, and 1% have hazel eyes. 

Eye colour depends on the amount of melanin, or, pigment, in the iris;

Brown eyes have a large amount of melanin 

Green eyes have a medium amount

Blue and hazel eyes have a very small amount.
