A few other people have alluded to this, but I'll just say it again. Eye color is NOT Mendelian like everyone learns in school. That means that there is not just 1 gene that controls eye color. So even though light-eyed parents usually have light-eyed children, there can be some brown-genes in there that are not expressed. Since there are multiple genes that come into play, a "brown" gene may not be dominant in one combination of genes, resulting in a blue-eyed parent. If the other light-eyed parent has a different "brown" gene the two could combine to have a brown-eyed child.
Case in point: I have blue-green eyes. DH has green eyes. DD has brown eyes. It is completely possible, though rare. |
We were just discussing this in my house as I recently discovered my husband's parents both had blue eyes. He has brown.
My whole family has green eyes. DS has blue. The postman has brown-black eyes. Is it possible DS is his? Oh no... |
okay, so I'm the previous poster. Hilariously, the eye color calculator doesn't allow my husband's parents to have blue eyes and his eyes be brown. It says EYE COLOR ERROR. I guess I don't know for sure, but he looks exactly like pictures of his parents so I'm pretty sure he is theirs... |
20:10 here. I'm 100% positive that my daughter is mine, and she's got brown eyes. DH and I have light. The calculator must have been built by a high-school student who learned the Mendelian eye-color chart. |
Are you sure you aren't adopted? ![]() ![]() |
I am bright, bright blue. DH is brown. One child has light green eyes, the other, dark green.
I know a woman who is blue, husband is brown, baby is blue. So brown is not always dominant. I think recently researchers have stated eye color is a bit more complicated than originally thought, genetically speaking. |
Look at mixed afro-american children who have such beautiful brown skin and green or blue eyes. Clearly, if our old beliefs about eye color held true, brown would trump every time, right? |
Oh, and I just did the "eye color calculator" and it says I should only have had brown eyed children. (One is light green the other dark green). So clearly they don't know jack. |
DH has bright blue
I have brown. Both sons have light blue eyes. There's many blue eyes in both our family. |
OP - how old is your child?
An infant's eye color may change. |
