Wondering about when the blue baby eyes leaves and you can see what color eyes they have. My beautiful little redhead, Kylee, is one month old and i have always thought red hair w/ green eyes is so pretty. I was thrilled when she got her daddy's dark auburn hair, but I cant tell if she has green or will have my hazel eyes. Either one would be really pretty on her, but I am dying to know.

My son's doctor said his eyes can change up to about 3 years old. But, he said that usually by 6 months the color is set.

I was wondering he same thing, I have very dark brown eyes and my husband's eyes are blue, and baby's are gray. Can't tell at all which way they're going but she's only 23 days old :s...Of course I don't really mind either way but I'm secretly hoping for her daddy's eyes :)

My daughter's eyes are still slate gray at 3 months...mine are a very light brown, my husband's are a ver y deep blue...I hope she gets his color, but I think she's gonna get mine, cause she has my eye shape.

My daughters eye color was set at about 5 months, I was kinda hoping for my light green eyes but they are almost black ;-)

I was wondering the same thing. My book says around 3 months. My daughter has almost gray/dark blue eyes at 5 wks old but both her dad and I have bright blue eyes. I can't wait to see if she gets them too!

I believe if both parents have blue eyes, their children can only have blue ones as well.

Most caucasian babies are born with blue eyes that later change colors. The time frame varies for when the eyes will change colors --IF they will. Just because both parents have blues does not mean the child will have blue eyes, unless blue is the only eye color that anyone in their family EVER had. Blue is actually a recessive gene, with brown being the most dominant eye color. Although both parents having blue does increase the probability of blue eyes, it does not make it a definite. How genes come together is a toss up every time, that is until were are able to genetically engineer a child to our personal preferences.

My first daughter was born with brown eyes and they've stayed the same. My second was born with blue eyes, and now they're kind of grayish brown (she's 3 months). Your eyes can change color when you're older, too...mine were brown as a child and they're green now.

Two blue eyed parents cannot have a baby with brown eyes. Due to the fact that brown is a dominant trait and if the parents had that gene to pa__s, there eyes would have been brown. However, two brown-eyed parents can pa__s their recessive blue gene and have blue eyed babies. I have brown eyes, hubby has blue. My mother had blue eyes, my dad had brown. I pa__sed my recessive gene I got from my mother and my son has beautiful blue eyes =)

I do know that most caucasian babies are born with blue eyes. Most babies eyes aren't set until about six months. I have dark brown eyes and my husband has blue, and our little girl was born with dark gray eyes. At her two week appointment the pediatrician told us that her eyes would be dark, and so far they have only gotten darker. I am a__suming she got my eyes. She is almost 8 weeks old and her eyes get darker by the day.

Biology major is right on the dominant/recessive traits. They don't have to be blue, but green, gray.. a light color. My son will probably have blue eyes. He was born with birght blue eyes (not dark) and they just seem to be getting lighter.

It is possible for two blue eyed parents to have child with brown, or any other color, eyes. Brown is just not very likely. At one time scientists thought that a single gene pair, in a dominant/recessive inheritance pattern, controlled human eye color. The allele for brown eyes was considered dominant over the allele for blue eyes. The genetic basis for eye color is actually far more complex. At the present, three gene pairs controlling human eye color are known. Two of the gene pairs occur on chromosome pair 15 and one occurs on chromosome pair 19. The bey 2 gene, on chromosome 15, has a brown and a blue allele. A second gene, located on chromosome 19 (the gey gene) has a blue and a green allele. A third gene, bey 1, located on chromosome 15, is a central brown eye color gene. Geneticists have designed a model using the bey 2 and gey gene pairs that explains the inheritance of blue, green and brown eyes. In this model the bey 2 gene has a brown and a blue allele. The brown allele is always dominant over the blue allele so even if a person is heterozygous (one brown and one blue allele) for the bey 2 gene on chromosome 15 the brown allele will be expressed. The gey gene also has two alleles, one green and one blue. The green allele is dominant to the blue allele on either chromosome but is recessive to the brown allele on chromosome 15. 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 model 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 cannot explain how two blue-eyed parents can produce a brown-eyed child or how eye color can change over time like in Jbears case. 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. There are other factors in determining eye color that have not been worked out, like where do hazel or gray eyes come from? Obviously there are other factors contributing to eye color, that make it possible for blue eyed parents to have a brown eyed child.
