As a green eyed person, I’m curious about this. Brown eyes are dominant and blue eyes are recessive, so how would green eyes be classified?
In: Biology
I think that they’ve moved away from labeling eye color as a single gene trait, and it’s believed to involve multiple genes, meaning eye color can’t as easily be labeled as purely dominant or purely recessive anymore. That being said, it’s probably still true in most cases that brown is dominant, green is recessive, and blue is recessive. I know that blue is recessive to green as well. So green is still considered recessive, it’s just dominant over blue.
And yes, it is a mutation. I believe it involves the same mutated protein that makes blue eyes appear blue. It’s why some people can have eyes that are blue-green, or even eyes that seem blue in some light and seem green in other lights.
