Is it possible for two parents with brown eyes to have a child with blue eyes?

Question

Please provide factual information to back up your answer. Thanks!

Answer 1

Yes, it is possible for two brown-eyed parents to have a blue eyed child. Even if brown eyes was dominant over blue eyes, as originally thought, two brown eyed parents could produce a blue eyed child, as long as both parents were heterozygous (having a brown eye gene and a blue eye gene). One-fourth of the offspring of two heterozygous parents will have the recessive trait.

In reality, eye color is determined by at least four genes, which is why eye color can be blue, gray, hazel, green, brown, amber, even violet. The combination of these four genes determines what your eye color will be.

Answer 2

Yes it is possible. Blues eyes are actually a recessive gene. But if the parents have any family history of blue eyes, then the trait can manifest in a child with blue eyes.

Answer 3

Absolutely! Generally, brown eye color is a dominant trait. It only takes one gene to make a person's eyes brown. Blue eye color is a recessive trait, so it takes two matching pairs of genes to manifest blue eyes. So when the parents both have only one brown eye gene, it is possible to have a blue eyed child.

This is an over simplification, but generally true.

Now, those blue eyed parents with a brown eyed child. Someone is over due for a conversation.... =)

Answer 4

Yes, the child would have to get the recessive gene from both parents in order to have an unusual eye color.

Answer 5

maybe,because the chromosome that determines the colours of the iris is recessive,eg. parents with blue eyes and black eyes may have children with purple eyes
this is because the black eye colour have to be two chromosomes which is coded for black,which is double recessive to allows it to become black.

Answer 6

Yes it's possible.

Answer 7

yes

Answer 8

YES
