Are gray eyes the same as blue in terms of genetics?
June 28, 2007:
I read your article entitled Don't it make your brown eyes blue? Blue eyes are caused by changes in the OCA2 gene and found it extremely interesting. I have another combination to throw into the mix. Can you explain the genetics of an individual with one blue eye and one brown eye? David Bowie is one of these individuals.

How is it possible that I have blue eyes when my father has brown and my mother green? My grandma on my dad's side had blues and ONE of my uncles does, as well, but I don't know how I got the gene for blue if my Dad's genotype is Bb and my mother's is Bg.

Why did the very blue eyes of a kid become brown when he grew up?

Has any progress been made in explaining eye colors other than brown, blue, and green? I've seen dozens of explanations of how the gey (EYCL 1) and bey2 (EYCL 3) genes are supposed to work, all with the disclaimer that this model doesn't explain colors such as hazel, grey, or black (not to mention violet, yellow, or very pale blue). Are the pigments responsible for some of these colors thought to be related to specific genes? Can there be more than two alleles for a gene, such as green, hazel, or blue? Has anybody studied the heritability of unusual eye colors?

I hope that your explanation can clear up some confusion in my family. I have brown eyes and my husband has blue eyes. We have 3 daughters: one has blue eyes, one green and one brown. Everybody says husband,s genes are stronger so that explains the blue and green, but what about the brown?
October 8, 2004: Why do I have blue-eyes? I am an African-American. I am 37 now, it's always been a shock to many. I was born with natural blue-eyes. I am not light skinned at all; I am a brown skinned woman. People are amazed that they are blue just like how white people eyes are. I have a 15 year old and he has one total blue-eye, (the right eye) and the other eye is half brown and blue, weird right?
I went to the Georgia eye Institute in Savannah. they took lots of pictures of my eyes and recorded in their book. How in the world did my eyes get this color? And do you think that I can do an eye commercial or something of the sort?
July 7, 2004: My eyes were medium brown when I was younger, but a while after I hit puberty they changed color slightly. They are now a really dark brown-hazel. Mostly, they stay a slightly greenish brown, but occasionally, they go to a bluish brown-green or a really dark brown-green. Why is this?
My mother's eyes are dark brown, but my father's eyes are hazel. They sometimes change color from light blue to bluish green to dark blue, etc., depending on what he's wearing. Why do hazel eyes seem to change color?
I had clear blue eyes until I was about 7 years old. One morning before I left for school, my mother noticed that my eyes were a clear emerald green. The change must have occurred fairly quickly for it not to have been noted as it happened. My red-haired father had brown-with-slight-orange-tint eyes and my brown-haired mother had darkish, muddy-blue eyes. How/why did my eye color change? I don't know anyone else whose eyes changed color after the baby months.

How did I get green eyes? I understand that blue is recessive and that in theory all children of two blue-eye parents should have blue eyes. But, what about green? My parents are blue-eyed and have 2 green-eyed children and 1 blue-eyed child. And yes, he is my father. My high school Bio teacher embarrassed me by announcing to the entire class that he couldn't be when we studied eye color. So, how did I end up with green eyes? Thanks!
Is there any possible way for two blue-eyed parents to have a green or brown-eyed child?
Is it possible for a green-eyed person and a blue-eyed person to have a brown-eyed child?
One day my father's first cousin and I were discussing our Swedish background. This led to discussion of eye color. She said, "You know, both my mother and father had blue eyes." I looked into her eyes and they were dark brown! I thought I knew enough genetics to know that blue + blue yields ONLY blue eyes. I called my father that night (a physician) and he said he had never thought about it, but now that I mentioned it, my great-grandparents used to tell the story that her mother had thought she had been given the wrong baby at the hospital in Chicago (1927) Her sister had blonde hair and blue eyes and used to tease her about being adopted (she wasn't). She had bright red hair and brown eyes. She must have been the wrong baby!? Can blue eyes + blue eyes = brown eyes? I would never tell her what I suspect, but I am curious for my own sake. I suspect that in downtown Chicago in 1927, she was actually an "O'Brien" instead of a Peterson.
June 18, 2004: My eleven year old daughter was born with blue eyes. When she was about five months old one eye began to turn brown but the other one stayed blue. She now has one predominately blue eye with a touch of brown in one area and a predominately brown eye with a couple of little blue swirls. I have always been curious about what caused this.
