This is a common misconception. It's probably more likely that a brown eyed kid with two blue eyes get it is adopted, but it isn't necessarily true. If your dad has homozygous mutation in gene 1 that causes blue eyes, but gene 2 is homozygous normal, and the mom has a normal gene 1 and a mutation in gene 2, both homozygous, you could be heterozygous for both gene 1 and gene 2 and have brown eyes, etc. The genes are OCA2 and HERC2 in case any of you wanted to look into it.

How can you say science ruins anything? Especially since it gave us devices that literally slash air so fast that lift is achieved and the device is powered by constantly exploding dinosaurs.

Is it possible if the kid's mother cheated or if they used a sperm donor?
User avatar #49 - Furubatsu (07/24/2013) [-]
Receive genes. (I know brown is dominant, just listen)

One set of grand-parents, one is brown eyed (with a blue/green/grey gene as well) and the other has blue/green/grey/whatever eyes.
Due to a genetic fluke the next generation has the lighter coloured eyes, but can still potentially pass on the brown eyed gene.
Same/similar with the other parent.

Or do I have to go back to secondary school and have a go at my teacher for being wrong?
User avatar #56 to #49 - noblexfenrir (07/25/2013) [-]
This is the main problem though "Due to a genetic fluke", in cases like this we lean towards the majority of cases (This specifically would be like 95<? % of the time). Yes you are correct, but you will only really see this occur with dual brown eyed parents, not two blue eyed ones.

The reason for this is because brown is "pseudo-dominant", and will stay dominant unless two factors are satisfied, first the male has to have a father who has a dominant eye colour, let's say blue. Then the female must have a mother that also has the same dominant colour eye, so again, blue. Now the chances of blue appearing in the child have increased greatly. (Nowhere near enough to make it dominant in the child, but enough to make it possible for it to have blue eyes, it will more likely have green eyes actually, or hazel over blue, but the chances are there.

So, my mother has brown eyes, my dad has green eyes, my sister has blue eyes and I have brown eyes. Who's adopted again I'm confused.

#22 - thewasupman ONLINE (07/24/2013) [-]
I've looked into this a lot, because my parents have blue and green eyes, and mine are brown which "shouldn't be possible". They insisted I wasn't adopted, and after further investigation my biology teacher and I found that there are like 4 different genes that relate to eye color allowing for variation.
User avatar #16 - reginleif (07/24/2013) [-]
Highly unlikely but two blue eyes can have a brown.

My mum has brown eyes and black hair (Vietnamese) but both my sister and I have blue eyes and blonde hair.
My mum's dad was white apparently.
So no one believes that we're partly Asian.

I don't feel like researching into this but I don't believe what the teacher said is true. We learned something in biology about recessive genes and the likelihood of people with certain genes having kids with the same genes. I don't remember most of it but until I look into this (or one of our fj smart peoples gives me a little science lesson)imma call bs.
#31 to #1 - anon (07/24/2013) [-]
Both parents are homologous for the recessive blue gene, the brown eye gene is missing for them. Thus a child of theirs wont have brown eyes but will instead always have blue eyes.
User avatar #68 to #1 - useroftheLOLZ (07/25/2013) [-]
a A gene and a A gene will always produce a child with an A gene, a b gene and a b gene will always produce a child with a b gene, a A gene and a b gene will most likely produce a child with a Ab gene, since blue eyes are solid b genes, it is pretty much impossible for the child to have brown eyes. Also, blue eyes are a genetic mutation, just to let every one know.
User avatar #2 to #1 - shiningfinger (07/24/2013) [-]
Pretty sure blue eyes are recessive to brown.
#52 to #2 - anon (07/25/2013) [-]
It is still possible that both parents carried a blue eyed gene; redessive, and then carry it on to the child.
#47 to #2 - flyingtomatoesss (07/24/2013) [-]
True, but eye color is a polymorphic gene meaning the codes for it are located on different chromosomes. However, having blue eyes is not a color gene per say but in fact the "absence" of pigment on the eye meaning that the genes for eye color are completely deactivated by another, in this case single point gene, that causes no color to be expressed thereby "defaulting" to blue. That's why almost all brown-eyed individuals are born as blue-eyed infants since their genes for coloration have not taken effect that early in life.
Thumb me down if you want but that's how it works from a genetics major
#24 to #2 - bigmanblue (07/24/2013) [-]
eyup thats right
you can only have blue eyes if you have no other pigment coded into your genes
in other words 2 blue eyes always = either blue or grey eyes (because blue yes are just pigmentless)
#20 to #2 - igelior ONLINE (07/24/2013) [-]
allright i just had a written exam on genetics last week so listen to me:   
two blue eyed people can have a brown eyed child - however it is rather unlikely. yes the allele for blue eyes is recessive i.e. if you have one allele for brown eyes you got brown eyes so you can only have blue eyes if you are homozygous for blue eyes (let's say bb) now if you cross two blue eyed people that would be bb x bb they can only have bb children. HOWEVER if the parents are homozygous for different genes that are both necessary for the exprimation of brown eyes e.g. bb RR x BB rr (where R and B are dominant) the metabolic pathways that would lead to brown eyes are interrupted in both individuals so both have blue eyes - however their kids can be Bb Rr (due to recombination in gonosomes) and they will have brown eyes - this is called epistasis. Also you can have a revertant mutation that would turn a recessive b allele into a B allele (recessive alleles are usually functionless mutations of a dominant allele) but that's even more unlikely sooooo yeah...

Everyone is sitting here correcting me, but if you read down, I was keeping it simple.
#21 to #20 - offonatandem (07/24/2013) [-]
eye colour is more like skin colour in the way it's determined. The **** they tell you in school about BB bb is just ******** to simplify it. There's loads of different alleles that contribute to different shades of brown/blue. Essentially, blue eyes have very little pigment and brown eyes have a lot, hence why it's unlikely to have a blue eyed kid if both parents have brown eyes.
#23 to #21 - igelior ONLINE (07/24/2013) [-]
yeah i had to simplify it as well but that's basically how it is - sorry i couldn't fit the entire human genome in a post ;-)
User avatar #3 to #2 - fireprincess (07/24/2013) [-]
Well yea. And since its recessive it's more likely there are Brown eyed people in there ancestry. Which would make it possible to have Brown eyed children.
User avatar #4 to #3 - shiningfinger (07/24/2013) [-]
>Both parents have blue eyes
>Blue eyes are recessive
>bb + bb = Bb, BB?
It would be impossible for them to have a child with brown eyes.
User avatar #10 to #4 - BlahDude ONLINE (07/24/2013) [-]
Actually, although eye color does follow this pattern very closely, it's not perfectly modelled by the simple idea of "recessive and dominant", in fact, very few human traits are.

Even though it is incredibly rare, it is still possible for two blue eyed people to have a brown eyed child.

Human genetics is complex as **** , no wonder Mendel stuck to pea plants

User avatar #84 to #83 - oliveirajo (07/25/2013) [-]
You shall know that such an modification of the eyes colors ( Blue is not supposed to be) is incredibly rare. Since the probability that the mutation would happears randomly is stupidly weak, it is rather admited. I think you should start learning more about the fact scientists said that this ''Blue eyes'' mutation will dissapear over time. I must say your analogy is awfully wrong, please shut the **** up.

stop me if i'm wrong, but couldn't he have blue eyes anyways? if both parents had one blue and he inherited those?

User avatar #63 to #53 - sketchE ONLINE (07/25/2013) [-]
lets break out the old punit square. let b represent blue and B represent brown
b b
b bb bb
b bb bb
as seen here two parents with blue eyes could not pass on a brown dominant gene since blue eyes is recessive and requires two aleles

B B
B BB BB
b Bb Bb
In this one two brown eyed parents would not be able to pass on blue eyes since both of them have the dominant alele but only one has a recesive alele

B b
B BB Bb
b Bb bb
in this one a blue eyed child is possible with two brown eyed parents since both possessed a recessive alele

so yes you are right parents with brown eyes can have a blue eyed baby its just not very common. the post however is about the opposite
