Which Eye Color Is Dominant?

Brown is the dominant gene.

My eyes are blue/green and my ex's are brown, but my son has blue eyes. You have to table the entire family to really have a good idea of what color your children will have. And even then.... Lol

I always heard brown, but my mom had 4 children only one had her brown eyes. Me .I had 3 children and 2 of them brown and 1 with blue. Then my 2 brown eyes had their dad's blue eyes on their first children. Not the mother's blue, or the dads hazel, they had their dads blue eyes in our grandbaby's. Exact same color. So, we are all saying my youngest--the blue eyes, will probably throw a brown eyed child the first time.

Either way, scientifically, brown is the dominant gene. Lol all others are recessive.

Wow. That gets confusing lol. As far as the "table" goes, everyone in my husbands background has brown eyes because he is latino. And on my side both my parents and my 3 brothers and myself have hazelish(is that a word?) eyes, I know my dads mom and sister have hazel eyes, dunno about my grandpa...He died when I was 5. As my moms mom, she's also got hazel.
Hmm, I guess we'll just have to wait and see. I just hope this poor child doesn't have hair like me lol. I hate my hair, it's very thick and curly. It's a disaster to work with. I hope she's got straight hair. Time will tell! Thanks for all the replies!

Yeah, we get our eyes from the italian, and native american.--my dad had green and my brother has green. The other 2 kids their dad had blue, and they have blue. But my mom's eyes were actually black she was 1/2 italian, and my dad had green eyes he was 1/2 native american.

My grandma and grandpa apparently had the same eyes which are hazel...I think there two sons had brown eyes (not sure...My one uncle died when I was little and my other uncle i've never really look at them) I know my aunt has dark brown eyes and my moms came out emerald green (very odd- but my grandpas mom was irish...So it was probably from his family) my grandfathers father was half native...So I am thinking he had brown eyes...Me, my girl cousin and boy cousins have hazel eyes...My other girl cousin got her moms blue eyes. Me and my cousin with the hazel eyes also have the exact same hair color (medium browm) so people always think we are sisters (only she is like 12 years older...Lol) I am the first of us "kids" to have a baby...So it will be interesting to see what it looks like. My ex boyfriend was almost full native...But he wasn't overly native looking and had some white features. His skin was tanned...But it wasn't really dark, he has dark brown eyes and dark brown hair...And is very tall...I'm short and my hazel eyes change color to green...I would love for my baby to come out as white as me with his lovely hair (its so dark and thick!) and my eyes...But we'll see...Since brown is dominant...I am thinking she'll have dark brown hair and eyes...It'll be kinda dissapointing...But oh well lol.

Ok thats crazy because I have really light brown hair... And the father of my baby has dirty blonde hair, but when he was a baby his hair was white. I have light light brown eyes and he has hazel. Well his other baby mama looks almost identical to me..Lol and their daughter has white blonde hair with hazel eyes. She looks nothing like her and exactly like him. It's actually scary cause she sorta looks like a little boy. Lol so he carries some pretty strong genes plus he's older then me. So im really excited to see if my baby comes out lookin exactly like him. We can only hope that he/she gets his looks and my brains...Lol

I learned in high school science that brown is indeed the dominant gene in heredity. We actually had to do the whole chart thing someone mentioned for a lesson.

It is funny how genetics works, though. One can carry so many differing genes, even though not presenting any characteristics of that gene. For example, a mother and father can both have blonde hair and blue eyes, and they can have a son with red hair and green eyes, if those are the genes the parents silently carried that become expressive during the fertilization process.

Lol teach we did that too... The little work sheet in science class were u figured out what the parents ahd then what would the baby have. Lol

Eye color is seriously confusing. There's too many possibilities. Maybe this chart will help. I found it surfing before when I was trying to figure out what color eyes my little papoose will have...

Www.Genetree.Com/about/eye -color-chart.Asp

Another thing I forgot my mom has natural brown hair and her first husband my sisters dad has brown hair now but it was blonde when he was younger, and my mom has dark brown eyes and her first husband has blue eyes. My sister has brown hair and blue blue eyes...Lol there beautiful im jealous...Lol but she also had blonde hair when she was a baby up to 4 yrs old and it changed. So im not really with the whole thing that brown is more dominate then most colors cause things can happen...Lol

Actually teach was probably the closest to being right in here, I had a friend who wrote a paper in college on this topic and it became a very big discussion in class.

Second off I want to say that genetree.Com sight chart about eye color says it originates from the 1800s. And though its slightly accurate on alleles the table it represents could never be used and any accuracy that came out of it would be chance.

If you would like to know the scientifics on what actually decides the eye color I will explain it as simple as I can without losing anyone...

The eye color is decided by the amount of pigment (called melanin) in the iris of the eye. For example: blue eyes have little pigment in them while brown eyes have alot. Melanin is a dark brown pigment that is deposited on the front surface of the iris. If a lot of melanin is present, the eye will appear brown or even black. If very little melanin is present the iris appears blue. Intermediate amounts of melanin produces gray, green, hazel or varying shades of brown. And what decides the amount of pigment in an iris is a number of different genes.

Like the genes when a sperm and egg cell is created they each have a haploid number of 23 chromosomes and during pregnancy, the fertilized egg undergoes a series of changes including multiple cell divisions and differentiation of cells into the different organ systems. The result is a baby whose cells each have 46 chromosomes. one chromosome of each pair is inherited from the baby's father and the other from the mother. And we all know genes are what determine the observable characteristics (eye color) in humans.



this means that there is a dominance order among the two gene pairs. If a person has a brown allele on chromosome 15 and all other alleles are blue or green the person will have brown eyes. If there is a green allele on chromosome 19 and the rest of the alleles are blue, eye color will be green. Blue eyes will occur only if all four alleles are for blue eyes. This explains the inheritance of blue, brown and green eyes but cannot account for gray, hazel or multiple shades of brown, blue, green and gray eyes. It can't explain how two blue-eyed parents can produce a brown-eyed child(which genetree.Com says 2 blue-eyed parents can not have darker eyed children). This suggests that there are other genes, yet to be discovered, that determine eye color or that modify the expression of the known eye color genes.

So unless you know the specific order of those two pairs of genes your not going to be able to accurately make up a "table" for predicting the eye color of your baby.

Im sorry for the exhaustive post but I just like to get facts out there rather than alot of assumptions that make people go in circles.

I am impressed! Thanks for all that info, I have to say that is the most thourough reply i've ever read.

Cool, thanks. I didn't really pay too much attention, I was just trying to get an idea of the possibilities.
I'll just leave it as any color's possible.... Darn that sux :wink:
