Can a brown eyed Father and a Green-eyed Mother produce a Blue-eyed child?

Question

I heard somewhere that a brown-eyed parent and a green-eyed parent could not possibly produce a blue-eyed child. Does anyone have the answer?

Answer 1

It's entirely possible for a child to receive a completely different variation (like eye colour). When a child is conceived, they receive two of each gene, one from each parent. One gene is said to be dominant so if there are two different genes, the dominant will take the place. Brown eyes is a dominant gene, however, if the child were to receive two blue genes, then there would be no dominant gene (since they're the same) so the child would have blue eyes.

When the dominant gene takes the place, the other gene remains in the chromosome but is not seen. This is the recessive gene. So if both parents have a blue eyed recessive gene and they both pass this onto the child, the child will have blue eyes. It's not likely but possible.

Incredible thing, the human body.

Answer 2

If both parents have the recessive blue-eye gene then yes, but both parents have to have this gene. It takes 2 recessive to make a trait happen. Brown eyes are dominate, so if you have 2 parents with 1 dominate brown eye gene each, the chances are greater that the child will have brown eyes. Unless both have the recessive gene, the the child has a 1/4 chance of having eyes with the recessive trait. My stats might be off but that is pretty much what I learned in biology last week.

Answer 3

Blue eyes is a recessive gene meaning that you have to carry it on both genes in order for you to have them. This means that you need to get one blue eyed gene from each parents. If you and your husband are both carriers, and both pass that gene to you child, then they will have blue eyes. The same goes for blond hair. Now 2 blue eyed people can only have blue eyed children since that's all they have to give the child

Answer 4

Absolutely! I believe what you mean is if two parents are brown eyed. The eyes of both parents have to be pure brown. they cannot produce a blue eyed baby. But parents with brown and green eyes can produce babies with any color eyes.
Hope this helps.

Answer 5

It's possible that both parents carry the blue eyed trait, which is recessive. If those two genes from the parents happen to get picked, the child can have blue eyes.

Answer 6

Yes, they can produce a blue-eyed child.

A child has a 25-50% chance of having blue eyes when one parent has brown eyes and the other parent has green eyes. The genotype of each parent ultimately calculates whether the likelihood is 25% or 50%.

Take a look under "Example Crosses" on this website: http://www.athro.com/evo/gen/eyecols.html

Answer 7

Yes, every single person has 2 eye color traits. They have a Dominant eye trait, and a Recessive eye trait. If the brown-eyed parent (Dominant = brown) and the green-eyed parent (Dominant = green) both have blue as the Recessive trait, the child COULD be born with blue eyes. Then, her eye color would be blue (Dominant) and would have either brown or green as their recessive trait.

Answer 8

It's possible. genes for blue eyes are recessive and ones for darker eyes are dominant. You can have one dominant gene for brown and one recessive gene for blue. If you have a baby with someone that carries a gene for blue eyes you can have a blue eyed baby. Same thing with hair colors. Here is a site about two mixed people who had a white baby and a darker baby. Genes can do some weird things.

Answer 9

I DO know that a brown eyed parent and a blue eyed parent can produce a green eyed child..So why not!

Answer 10

Listen to Melissa. I don't need to rehash it, but biologically speaking, she is 100% correct. Recessive genes are unique in that if you have it, that is all you have, whereas dominant genes hide what the other gene is, possible the same, possibly recessive. If you have brown eyes and you produce a blue eyed child, you have answered what the second gene in your makeup is.
