Why I have blue eyes?

Somebody in your family must have blue eyes, I got my green eyes from my Dad. As for the genetic reason that's way out of my league. You must have pretty eyes because that was suppose to be one of Elvis's best features.

Pigments in your eyes serve the purpose of screening out excess light.  All eyes "should" be brown.  Genetic defects in certain pigments results in a variation of eye color either by incorrectly transcribing pigments or not expressing genes that should be expressed.

I have a green eye. Sometimes it goes blueish, but it's hardly ever brown. I have another one that's just like it!\n((Guess Malibu wins this one!))

Well,i as well love my eyes.They are different,they are blue and change shades of blue depending on my mood.\nWow,as for what i dont like,im not sure,not to sound cocky or anything.I just find that everyone should love themselves for how they are.

your chances are 50% because you must carry the reccessive gene for green/blue eyes.  your mother has green eyes she must carry dominant brown and recessive blue and father's blue eyed.  father has two reccessive blue genes, you have a dominant brown gene and reccessive blue. good luck...u will probabley get green eyed! mix of the two!!

normally blue because the oxygen diffuses blue light most.

I haven't seen that personally.  Actually, according to scientific studies, people with lighter eyes (especially bright blue) tend to have more eye problems than any other eyecolor.  There could be some vitamin or mineral deficiency that Asians have that I am unaware of though.

For the same reason that some people have brown eyes and others have blue. Its the type of plant they are.

I've known several African-Americans with blue eyes.  It's not common, but it does occur.  Most African-Americans are not purely of African descent.  It's a recessive trait, so both parents have to have blue eyes somewhere in their family tree.

my own understanding to this is - and i might be wrong - it has an affect. i based this on Albinos, they lack pegimintation (melinen) in their skin and eyes (which gives them pink or red eye colour) and they have major eye-sight problems and sun can affect them alot. so i would assume the less pigement u have (i.e. blue) the greater affect u will have by sun (even if it is very little) but surely there is a difference.

Light brown eyes have 1 dominant and 1 recessive gene (Bb). Blue eyes are double recessive (bb), so with two parents having light brown eyes (Bb + Bb), the odds of a child having blue eyes is 1 in 4.\n\nBb + Bb = BB, Bb, Bb, bb

Many babies are born with blue eyes that later change color. this is what happened to me, they were blue now they are hazel. Eyes change color just as hair does, and yes you might have hazel eyes

Its something to do with the eyes I think. Sorry I cant give any further info.

It may be possible some time to change the genetic make-up of someone. However, i think it would be easier to do this for eye colour. In its simplest for, Blue or Brown eyes are determined by which alleles are transfered from parents to child. There are two types of alleles: dominant and recessive. Dominant always trumps recessive. Brown eyes are dominant. So if one parent gives one Brown allele, the child will definantly have brwon eyes. For someone to have blue eyes, the Blue allele would have to be given by both parents.\nIt may in the future be possible to select alleles from parents. In this case, it may be possibel to determine eye coulour.\nHowever, it is more complicated to change hair colour. But with modern scinece, complicated doesn't mean anything, so i think in future, one will be able to select their child's hair and eye colour.

Brown-pigmented eyes are so dark that there could easily be green-eyes pigment there-and a previous answerer went into detail about the relative level of pigment, so there is no fear of infidelity.\nBut, in the case of kitty....\nNot to put too fine a point on it, but Im not aware of any genetic way two blue-eyed people can have a brown-eyed child normally... Blue eyes are recessive, being a very low level of pigment-If either parent carried a different gene, one that coded for brown eyes, then *they* would be brown eyed.  If you have brown eyes, but both your parents have blue eyes, I would suspect that one or both were not your biological parent.
