Brown is the dominant gene worldwide, when it comes to eye colour. But its way more complicated than that

What about us green eyed people?

I have green eyes.

forget the colour of the eyes..i'd say that figure relates more to the forecast indigenous(such as it is) population % decrease and that's conservative
the lunatics have long taken over the asylum(le mot juste in today's world)  |

Every blue-eyed person in the world descends from a single family that lived in modern-day Ukraine about 8,000-10,000 years ago.
Indigenous my arse. |

All eyes are naturally blue and all skin is white. Its only when the body gets the code to put melamine in for safety reasons that brown appears

Wouldn't eyes without melanin be pink, as there would be no pigmentation to obscure the blood vessels in the iris?
I'd understood the gene for blue eyes to be a mutation for a reduced volume of melanin rather than an absence of it. Re green eyes: it seems you receive two distinct genes for eye colour from each parent: one is brown or blue and the other is green or blue. Blue is recessive, so if the brown-or-blue gene gives brown from one parent and blue from the other, then the brown one takes precedence. Similarly if the green-or-blue gene give green from one parent and blue from the other, then green takes precedence. The final outcome is determined by brown always taking precedence over green. You can work out your own ancestry this way. My mother's eyes were brown and my father's green, but mine are blue. She must have received genes that were brown/blue from one parent and either green/blue or blue/blue from the other. She passed on blue/blue to me. Similarly my dad had blue/blue from one parent and green/blue from the other and, again, passed on two of the blues to me. All I can pass on now is blue/blue, as that's the marker of all four of my genes. |

Screaming - true about how we get blue etc, but scientists haven't yet worked out why we have colours such as hazel, more genes are involved there. I was convinced my boy was going to be green eyed like me, but I now know I carry the recessive blue gene too (or the milkman does).

Yes. Always wise to take a long, hard look at the milkman before making assumptions. Mother's brother has blue eyes, and father came from Ukraine, where the blue gene arose, so not implausible they really were my parents.
I suppose you can only really be sure if both the mother and father have blue eyes. Then the baby would also have to be blue (unless it's hazel - hadn't thought about that one). Are grey eyes the same as blue? A quick glance at Google says they might be, but can't be arsed to read it. Much easier with thoroughbred coat colours: one gene from each parent, bay or chestnut, with bay taking precedence, and grey as a gradual masking agent. |

just about everybody i know has blue or grey eyes 8/10 at a wild guess - even most brown eyes are technically a green colour when you look close .
pure brown eyes are very rare , as are vivid blue . |

By:
although i live in the East - so maybe more prevalent here - a bit like Scotchland ,it's same as red heads in Scotland /Ireland .
Red headed folk are nearly all found in those countries - something to do with so may cloudy days (see my weather report )  |

Sign in if you are part of the blue eyed "master race"

The milkman has always been very busy. Taking genealogy back more than a few generations is extremely speculative.

By:
Blue eyed women nearly always go for dark eyed males ,so the decrease is a fairly default situation, you would have to physically seperate the sexes genetically to retain a colour .
Same with hair colour - not often would a blone girl date a fair haired guy out of choice . Racially this is also seen with black guys dating white women (if i'm allowed to say that ) |
