Blue-eyed Humans Have A Single, Common Ancestor

So who shares a common ancestor with me? 

[Oshyan]

Wow, that's pretty crazy. Well, you and me are part of the club so far.

I'm not a geneticist but I do wonder about their assumption that because all blue-eyedness comes from the same "switch" then it was probably a single mutation that has been passed down. There's so much we still don't know about genetics and I wonder if there is the possibility that some genes might be more susceptible to mutation than others, in which case maybe the same mutation could have happened more than once?

Matt, we're related!

[NWsenior07]

Me too! One big happy family aren't we?

[dhavalmistry]

no offense but this ancestor must have had lot of "fun" back in his day! ....

Your son has blue eye but you don't. Ever wonder how that can be. My mom and dad both have brown eyes, I have very blue eyes, does that mean that they are not related to this same "common" ancestor as me? Something doesn't compute. On top of that both of my brothers and my sister have brown eyes.

[old_blaggard]

sonshine - this is entirely possible.  I don't remember the exact terminology (my last bio class was a few years ago ) but basically, if each parent inherited one brown trait and one blue trait from their parents, there would be a 25% chance of you having blue eyes (assuming brown is dominant).

I'm part of the blue eye brigade!

If I have green eyes, which is a mixture of yellow and blue as we all know, am I a "Halfling" then?

[Will]

Well if it is green I would imagine you are a wood elf.

[rcallicotte]

What if your eyes change between blue and green?   

[Harvey Birdman]

Sonshine - that's a standard recessive gene phenomenon. Who was the monk with the peas? Mendel?

hehe my wife, my grandma , my 2 grandmas have blue eyes... i don't... neither my daughter ^^
blue eyed parents can only have blue eyed children but brown eyed+blue eyed can have different colours ^^
