A woman has brown eyes and so do both her parents, her ex hubby has brown eyes and his mother brown and dad blue. Their child has blue eyes, i thought the mother needed 1 parent with blue also in order for the child to have blue?

Hi; I'm the one that asked the question above. I've been reading and from what i have been understanding is brown = B and blue = b and that in order for my hubby and his ex to have a blue eyed child they'd both need to carry Bb genes. WEll my hubby would be Bb as his mom has brown eyes and dad blue. But his ex wife has brown and so do both parents so wouldnt she be BB?? So wouldn't BB + Bb = BB??? Yes we are questioning paternity and have for a while and this just made us wonder more?

its like this amagin theres to blue genes and 6 brown genes your more lightly to get the brown and thus have brown eyes so if by say on in four chance they pick blue then he will have blue eyes

Have you ever heard of a recessive gene? Perhaps blue eyes is a recessive gene and it skipped a generation. it's definitely possible. MY dad has blue eys my mom dark brown. three kids all dark brown eyes no blue.

You got it back to front. Brown is domionant, blue recessive. To have brown eyes you can have 2 brown eye genes, or one of each. If you have blue eyes, you have 2 blue eye genes. If both brown-eyed parents have one blue and one brown gene, then one child out of 4 can expect blue eyes on average

If both parents carry a recessive blue gene then the baby can have blue eyes even though everyone in the family has brown eyes. This is a fairly common occurrence in Mexico where Spanish and indigenous mixes are common.
