Study shows that blue-eyed people share a common, single ancestor.

Count me in! And my husband!

I have blue eyes.
We are all mutants!
Schweeeeet!

Just thinking about this, there’s no way I could have been anything other than blue. Both of my mom’s parents, and their parents, and assumingly their parents ahead of time were blue-eyed (and I’m assuming this because they’re Icelandic and prior to that, Northern European). Dad’s parents were both blue-eyed as well IIRC. I’m gonna have to ask Dad about his grand parents.

So does this make all of us some sort of giant Blues Brothers kind of thing?

I have blue eyes (mother blue, father brown) - my sis got brown.
my wife has grey eyes (what causes that colour?)

my daughter has grey eyes.

My mother has blue eyes, and my dad has dark brown eyes. My older brothers got two different shades of blue, and I ended up with a hazel-like brown. I’m definitely unusual on my mother’s side, as blue and green is extremely common in Iceland (88% according to Wikipedia) and brown really is unusual; I can only recall one childhood friend from there that had brown eyes.

Edit: Ginger, although there are brown eyed people in Scandinavia, they’re few and far between (especially in Iceland). I’m guessing my brown eyes came from my dad mostly, and the heavy influence of my mom’s really pale blue eyes came through with the slightly green tones that I’ve got.

I have blue eyes… and so does my boyfriend. Fortunately, we live in South Carolina, where this sort of thing is more acceptable than elsewhere. My dad has blue eyes, and all his family. Mom has hazel eyes, which genetically are “not-brown”, right? Grandpa had blue and Grandma brown, although obviously she had a recessive blue hiding out there. Only one of her children out of four got the brown eyes.

I’ve got blue eyes too. :: waves to everyone else ::

Green/Gray/Hazel eyes come from a different mutation, if I remember Freshman biology correctly.

I’m always surprised at how long-lived this fallacy is turning out to be, since the simple dominance in eye colour was disproved years and years ago. My mother (a well-respected clinical geneticist) threw a hissy fit when she saw the eyecolour chart in my textbook 10 years ago, since even then it was already completely inaccurate and should’ve been replaced with something like attached/detached earlobes… it may not be as flashy as eye colour, but at least has the benefit of being true.

For one, if it was as simple as BB, Bb and bb, we’d have only brown and blue eyes with very specific characteristics. However, there are endless variations of blue, green, hazel, and brown (just look at the eye colour descriptions so far on this board), which would be impossible in a simple dominant/recessive trait.

We now know that human eye colour is a complex combination of partial dominance and there are usually a combination of several genes at work (similarly, hair is very complex with one gene’s having no other purpose than determining red/not-red… otherwise, we’d all be either blond or brown and nothing in-between).

Thank you for that. I was going to offer the same comment, but without the cite. My blue-eyed parents’ children included 2 hazel, one green, one gray, and the rest blue-eyed.

Wow.

My extended family is massive!

This is going to make the next reunion a logistical nightmare.

That’s neat but I’m not sure how to classify myself. I have green eyes with a ring of brown around the pupil. The only choices are blue, green, and brown.

At least I’m not an inbred mutant. :smiley:

Hello cousins.

Another gray-blue here <waves hand>.

I’m sad that my children - if I ever have any - will be doomed to have brown eyes, no matter what color eyes my future husband ends up having. Ah well. One can only hope my grandchildren have better luck.

/me comes in an hands sunglasses to all his blue-eyed, light sensitive distant cousins.

Of course we had more kids… Who could resist these baby blues? (the whole “Brown eyed girl” song is nothing more than an attempt to keep some brown eyed girl happy. The singer, had obviously just slept with someone with **superior ** blue eyes. :smiley:

Not necessarily. All it takes is one blue-eyed ancestor, a zillion generations back, lurking in your gene pool. Perhaps some enterprising Russian fur-trader found his way into your great-great-great-great-great-great-great-great-grandmother’s heart? Their child would have brown eyes, and unless a descendant married another person carrying such a gene, how would you ever know? But that lowercase b (debunked on the last page of this thread, I know, but work with me here) could be lurking unsuspected within your genes.

So I have brown eyes, but my brother and first cousins all have blue. Since I’m fairly sure I share genes with them, I have a sneaking suspicion you guys are related to me, too. And butler1850, I’m telling grandma:

:stuck_out_tongue:

I got an error message that says I can’t have brown eyes when my mom has blue and my dad has green. :frowning:

An email has been dispatched to my mother asking if there’s something she’s not telling me…

That’s what I remembered reading somewhere a while ago, but my memory was a little unclear on it, and so that’s why I posed the question in the first place–specifically that it’s about more than one gene.

Another inbred mutant checking in. Also both parents and all my siblings.
