If one parent has brown eyes and the other parent has blue eyes, what color eyes would their off spring have?

Question

If one parent has brown eyes and the other parent has blue eyes, what color eyes would their off spring have?

Answer 1

It depends on their recessive genes.

My husband has brown eyes and I have blue eyes. We have one blue eyed child and one brown eyed child. This means that my husband has a recessive blue-eyed gene. (Which we didn't know about)

You can't have a blue eyed child unless the brown-eyed parent carries that recessive gene.

Answer 2

Noremally the brown, because its darker, will over power the blue and the child will have brown eyes.Of course it will be lighter then the parent because the blue does hve some effect on it. lthough my dad had blue eyes and my mom had brown eyes but i have hazel eyes.

Answer 3

It would be neccessary to know the history of both families.

Generally speaking, if someone in the the backgroud on the brown eyed families genes is blue eyed, then there is a possibility.  

A blue eyed child must be carrying the recessive gene from both parents.  

Answer 4

I'm pretty sure that brown is a dominant trait and that blue is recessive meaning that brown will more than likely be the end result of the child's eyes.

Answer 5

Let me channel 6th grade biology for this one.

OK, Punnet square.  Brown(B) is dominant over blue (b).

Assuming that the Brown eyed parent has one dominant allele (B) and one recessive allele (b), there would be a 50/50 chance of having a blue eyed child.

If the Brown eyed parent had TWO dominant alleles (BB), then there would be a 0% chance of having a blue eyed child.

Answer 6

If the one with brown eyes has recessive genes for eye color such as green or blue, the offspring could have brown, blue, or even some other color.    If the brown eyed parent has only brown eye genes, the offspring will probably have brown eyes.
