can two brown eyed people have a blue eyed baby?

Yes, if they both have a blue ressesive gene in each one of their genetics. If this is the case, there is about a 1 in 4 chance of having a blue eyes baby. Of course, many babies are born with blue eyes and their eyes darker within days.

there are several genes in play\nlets start wtih eyes.. simply knowing his eye color is a start BUT you also need to know his parents eye color becuase he could be hiding a recessive gene..\nassuming he isnt - the kids will ALL have brown eyes.. but if he has a recessive blue gene then the kids have a 50/50 chance of blue or brown eyes...\nand so on for all genetics\n\nanyhow so in truth NOT only god.. but anyone with a knowledge of genetics can predict...\none thing though - get married before you start pumping out the kids.. and stop after 1 kid - the world is plenty crowded of people already

All newborns have a blueish hue to their eyes

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.

Usually by 6-9 months.  All three of mine were born with blue eyes and they stayed that way.  It doesn't matter if they are preemies.  Their eyes will change or stay the same color just like any other baby.

Your dad carried one recessive gene for green eyes, which his gene for brown eyes was dominant, so he shows that he has brown eyes.  you got one recessive gene from your mother, and the recessive gene from your dad, making you show for recessive, making you have green-blue eyes. the same way worked for your son

YES. Absolutely, despite all the answers you've received to the contrary. \n\nThe way blood groups are named, either your blood contains certain proteins (named A and B) or it doesn't - if you have both you are blood type AB; if you have only A you are A; if you have only B you are, you guessed it, B, and if you have neither you are blood type O.\n\nIf you have a gene for a blood protein, either A or B, you will have that protein in your blood. However, we have two copies of each chromosome, and it is possible that each parent has one copy of the A gene on one chromosome, and doesn't have it on their other chromosome (O). This means they will both be blood type A, since they each have one copy. However, if they have a child who happens to get the O chromosome from each of them, then the child will be blood type O. Mathematically expressed, each parent is AO, and on average their children have a 25% chance of being AA (blood type A and cannot have type O kids), 50% chance of being AO (blood type A but able to have type O kids), and 25% chance of being OO (blood type O).\n\nThis is the whole idea of recessive genes, which also explains why two brown-eyed people can have a blue-eyed baby without any hanky-panky going on.\n\nAs regards the Rhesus factor, i.e. the "+", again that is a recessive characteristic. The child must have received the Rh factor from his father, since his mother is negative. (NOTE that any Rh-negative woman who has an Rh-positive baby should get a shot of something called RhoGam, or WinRho, to prevent problems in future pregnancies.)

The children will not be "twins" (they will likely not look the same, though they may look similar in the way siblings do). This is because during meiosis, the genes in each haploid are random, from both parents.\n\nFor example, if both twin brothers had a dominant gene for black eyes and a recessive gene for green eyes, one twin might pass on a black eye gene to his child, while the other might pass on a green eye gene.

The 1:4 ratio others are giving you are wrong.  If there are two separate traits you want to find the recombination ratio for you need to do a punnet square (google that I'm not explaining).  Long story short, if the parents are heterzygous for the dominant gene (they carry one dominant and one recessive gene), there will be a 1:16 chance that the child will inherit *both* homozygous recessive traits.\n\nHere, the recessive traits are blue eyes and blong hair; dominant traits are brown eyes and black hair.

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.

* when a baby is first born, the eye still has not fully developed a dark pigment known as melanin that helps “color” eyes and skin. blue or gray eyes (which many caucasian babies have at birth) in a newborn mean that melanin is virtually absent within the eye’s colored portion (iris).\n\n* when your baby is about six months old, you’ll have a better idea of eye color as pigmentation begins to form and brown or darker eyes might appear. the baby’s eye color should be determined by about age one, although some individuals may experience eye color changes through adulthood.\n\n* people of asian, african-american, hispanic, or native american descent often have babies who are brown-eyed at birth because of darker pigmentation (melanin).

I think baby blues are the best, my daughter likes brown...\nThere you go...\n2 different opinions in the same family...

Darkness of skin is more complicated then just dominate/non dominate.\nIn the case of your nephew, his wife was carrying a recessive trait for eye color. B=Brown b=blue.\nSo let us guess that you brother has blue eyes...\nhe is a bb while his wife is Bb. so that gives four combinations...\nbB,bB,bb,bb half of which give brown eyes (bB &bB) and half blue (bb,bb) So you can conclude that you  sister in laws family has some caucasion ancesstors.\n\nAs to you and your husband. You must have aleast one non-dominate blue gene, if you brother has blue eyes. You husband will likely have dominate Black or Brown and some other gene. If you look at his parent's eye color and his siblings. If any of them have blue eyes you child can have blue eyes. It is most likely that you child will be darker than you and lighter than you husband

I don't think so. I'm not anyway. I prefer brunettes with blue eyes but I don't specifically look for that. I did find this though...\n\nI was reading "Why Men Don't Listen and Woman Can't Read Maps". It's a book written in a humorous manner, about the scientific differences between men and women, and why we act and react the ways that we do. \nanyway, in one sections it says \n" WHY BLONDES HAVE HIGH FERTILITY \nBlond hair is a sign of high estrogen levels and accounts for men's strong attraction to blondes. It is an indicator of fertility and is the likely explaination of the phrase "dumb blonde". Dumb blondes, so the jokes go, have high fertility and low mathematical reasoning. After a blonde's first baby is born, her hair darkens because her estrogen level drops. It darkens even more after her second child. The reduction in estrogen levels is why there are few natural blondes after age 30."\n\nisn't that odd? there's an actual scientific reason for why men are attracted to blondes, hmmmm. I don't know how it was determined about the low mathmatical reasoning part nor do I believe it. Hope this helped.

eye color is determined by two genes, one from the father and one from the mother. Blues eyes require 2 recessive genes, both blue. Hence, if either the mother or father has blue eyes one of the genes is provided. The other parent could have brown eyes, and still have a recessive blue gene. However if that parent has two dominant brown eye genes, the child will be born with brown eyes. The only garauntee is to have 2 parents with both blue eyes.

I've seen two people with pale purple irises, before the time of colored contacts. So it must be possible.

Such characteristics are shaped by the chromosomes you receive from your parents. There's a gene for every color of eye, color of hair, thickness of hair, color of skin, thickness of skin, shape of eyes, weight, height, life span, character, etc.\n\nEvery person receives information for every part from 2 people, so it will have 2 probably eye color, hair color, etc. Even when only one will appear, that person still can give the other gene to a child.
