How rare is it for caucasians to have brown eyes?

Brown is dominant but since 2 blue eyed parents cannot have a brown eyed child and 2 brown eye parents can have a blue eyed child it seems to make brown eyes rarer.

Assuming eye color is determined by a single gene:

It's not Link
Eye color: The color of the iris. The genetics of eye color are complicated. Eye color is polygenic. It is determined by multiple genes. The eye color genes include EYCL1 (a green/blue eye color gene located on chromosome 19), EYCL2 (a brown eye color gene) and EYCL3 (a brown/blue eye color gene located on chromosome 15). There are clearly other genes that influence eye color. The once-held view that blue eye color is a simple recessive trait has been shown to be wrong. The genetics of eye color are so complex that almost any parent-child combination of eye colors can occur.

Freshman biology classes still teach the old way because it makes for an interesting and 'real life' example of how genetics work. But it's PATENTLY wrong.

This is correct. And highly amusing. Because much like djheater pointed out, it is still being taught the wrong way, as is easily seen with the number of people who keep using this old theory. While the widely held idea on what genes causes eye color are easy for teaching people simple genetics, however it's wrong. Whats even more amazing (or fascinating) is that the current theories on which genes cause eye color, still cannot account for all the cases, like when both parents seeminly have the genes for creating just blue eyed offspring and yet produce a child ends with brown. Also they still cannot explain the cause for why one's eye color might change during their lifetime.

this is not true. there is more than one gene pair that play a role in the color of your eyes. So two brown eyed parrents (both with medium brown eyes) can have a child with either medium blue (i believe it's possible) or green eyes. And two medium blue eyed parents could have a medium brown eyed child
 
Both my mom and grandmom eyes changed from brown to blue and they're black :Q

I think mine may be changing too, I used to have dark brown eyes but they seem to be getting lighter
 
Well most of the white people I have met have blue/green eyes with brown being the minority. Anyway blue eyes arent as rare as some of you say according to the poll. Blue+Green 40%. Brown eyes are 43%. Hazel is probably split between brown and green/blue because a lot of people that have hazel eyes, their eyes changes colors from green to blue to brown to light brown.
 
Most of the white people that I know have blue eyes, so it's not as uncommon as a lot of you believe. It depends on exactly what white people you're talking about though. I live in Grand Rapids, Mi, where almost everybody is dutch or some other northern european, so probably 3/4 of people are tall and blue eyed. If you polled caucasians from more southern/eastern areas (ethnically) you'd find more browns.

Personally, I'm a bit of an odd case as everyone in my extended family on both sides has blue eyes. Somehow I ended up with one blue eye and one half brown, half blue.
 
I have brown eyes.

Quick, but shi t fact: All babies have blue eyes from birth, and it takes a short time for them to develop their pigment.

I had brown eyes right from the moment I launched myself from the womb. True story. Rare, apparently. But I don't know. Never looked it up.

Yeah, that's one of those "facts" that's definitely wrong.

 
I have greenish eyes. Mine are actually funky but in a cool way. They seem to change color depending on the light. I remember being in my bedroom and looking in the mirror and having hazel eyes, then walking across the hallway to the bathroom and then seeing green eyes. That was the most stark because it seemed to "change" in seconds.
I don't think it really changes, it just depends on how the light seems to refelct of my eyes. Usually they are a greenish type color.
 
I have grey eyes. Sometimes they look blue, sometimes they look green (usually depending on the color of shirt I'm wearing 😛).

Only because he said 'all'
Being born with Blue eyes is a caucasian trait, though presumably it could happen to anyone. Often it takes 9 months or so before the pigment fills the irises, more pigment is darker (brown) less is lighter (blue).
 
Brown is dominant over every other eye color, I believe. So, I guess it would stand to show with some simple algebra that brown eyes would have more numbers than blue eyes.
 
What I like about threads like these is it proves how very little of the information available is actually absorbed by an audience.

It's striking.
