Can 2 brown eyed parents have a light eyed child?

Question

Can 2 brown eyed parents have a light eyed child?

Answer 1

yes

Answer 2

Yes. The lightest shade of brown is what the color would be.

Answer 3

According to the quote from the link it is possible.

"Oddly, two parents with brown eyes could produce a child with blue eyes. How is that possible? Suppose both the mother and the father had the heterozygous alleles Bb—a dominant brown and a recessive blue. There is then a 25% chance that the child could inherit both parents' recessive genes, for a bb genotype—and a blue-eyed phenotype."

Answer 4

My mom had dark blue eyes and my dad has sort of grey eyes and I have hazel. Go figure. It's in the genes.

Answer 5

Yeah its possible, but not likely. In order for it to happen BOTH parents must have the blue eye gene in their immediate family. Then BOTH parents have to submit the blue eye gene, and only the blue eye gene, to their child. Anything other than the blue eye gene, for example green or brown, and their eyes will be either green or brown.

So yes it is possible. But two africans will not have a blue eyed baby in a million tries, if thats what your asking.

Answer 6

not really, and if they happen to have a child whith light eyed the unressesive gene showed up, Example tall parents can have smaller kids because in the past some one's relative used to be small

Answer 7

If I remember correctly eye color is not the same as other dominant recessive genes. Like hair for example. I think it was more like skin color where it is more of a mixture. But I don't remember completely.

Answer 8

Yes - if each parent is heterozygous for Brown eyes, then the odds are 1 in 4 that a light eye color could be produced.

Answer 9

yes!

both my parents have brown eyes and i have blue eyes.

Answer 10

yes, if a blood relative (however distant) has had light eyes

Answer 11

Yes. Lets say B = Brown (dominant), and b = blue(recessive).

If you have 2 parents whose genotypes are both Bb (heterozygous) then you will end up having 25% of the kids being BB (homozygous dominant), 50% of the kids being Bb, and 25% of the kids being bb (homozygous recessive).  The bb kids will be the one with blue eyes.

So there is a 25% chance that those two parents will have a blue-eyed baby.  But the 2 parents have to both be Bb for this to happen.  

Answer 12

yes but i don't think the chances are very high - but it depends on the parents' parents genes..

Answer 13

yes they can if some where in the past a family member had light eyes. but the chance and odds are very slim.  

Answer 14

Yes. Its just recessive genes that make a child's eyes light when their parents have brown eyes.

Both my parents have brown eyes, but my sister has green eyes.  

Answer 15

The answer is yes.

This is because blue (which is a light color) eyes is a recessive allele. That means that it can be masked by a dominant allele, in this case brown eyes. That means that, to have blue eyes, one must have only blue alleles (there is no dominant allele to mask it).

So, if both parents are heterozygous (they have both alleles) the dominant brown allele would show up. However, if both of them passed on the blue allele to the child, the child would have blue eyes. However, there should only be a 25% percent chance that a such a thing would happen (go look up a Punnett Square and you'll see why).

Answer 16

Brown is dominant to lighter colors however If both parents have recessive genes for light eyes and they pass on their recessive genes to the child then the baby would have light eyes..    

Answer 17

I think it depends if they have true brown eyes, rather than hazel. I think if the parents have hazel eyes then the child could have any colour because hazel is like a mixture of different colours. My mum has hazel eyes and my dad has pure blue, yet my eyes are very green lol. Depends on the genes I think, but I guess anything can happen!

Answer 18

Yes, and it is based on dominant and recessive genes.  Typically brown eyes are considered dominant traits, however, there are quite a few brown/brown people who have blonde hair/blue or green or hazel eyed children.  Look through the parents history, if you are able.  Was there a red headed green eyed person waaay back in the family?  There is that recessive gene.  And whoa when it pops up down the line.  :)  Your science teacher should be able to show you the graph (simple) that can be made to show Dom/Recessive.

      B     I        bl

B    BB           Bbl

gr   Bgr           grbl

Assume that B=brown, gr = green and bl =blonde.  Even a brown hair/eyed parent can create a green eyed blonde kid.            

Answer 19

yes

they can if they are both carring that jean it may not show on them or their kids in may not even show up until a few generations later  or if their kid has a birth mutation( no that doesn't always means being deformed or something)

Answer 20

yes its called a recessive gene, if either of the parents carry the blue eyed or green eye gene then that gene could show up later in their children.

Answer 21

yes you could but it is rare that it happens

Answer 22

yes! lol.. my dad has realy dark brown eyes as well as my mother, and i've got light hazel eyes... almost blue.

Answer 23

Both of my parents have brown eyes and i have blue eyes

Answer 24

Well I would automatically think not but, yeah it's possible. I mean, there are two dark haired parents who have a red-head and stuff like that.

Answer 25

Yes because if both the parents give the child the resessive gene then the dominate gene (brown) would obviously not show up, thus the childs eyes would be light

Answer 26

Lets consider the genotypes to be : Bb (father) x Bb ( Mother)

Do a punnet square and the ratios will be

3 brown eyes :1 blue eyes

So yes it is possible.

Green Eyes however are on a different gene i believe

Answer 27

yes! um duh
