Two people with the green eye color allele (brown is a variant) will have blue-eyed children 25% of the time. What you're looking for only works with two blue-eyed parents. They cannot have children with any other color eyes.

I still think it’s possible genetics are not as simple as people seem to think. Protein folding and mutation is effected by a lot of factors. Including environment.

Yeah, it's been a while but last time I took a biology class there were six alleles which determine eye color.

I honestly tend to agree. I think the dominant/recessive thing falls flat in a number of poorly understood cases. That said, it’s apparent that light-colored eyes are in imminent danger of being wiped out en masse like we’ve seen in Brazil. So I think we’re both right - the situation is sufficiently complex that the reality encompasses both our positions without contradiction.

I agree light colored eyes are in danger of being wiped out.

They are in this case. Two blue-eyed parents cannot have children that have another eye color. It's not physically possible.

Having blue eyes means you don't have the gene for green/brown eyes. It doesn't exist in your genome - recessive or dominant. You cannot pass on a trait for which you carry no genes.

I think it would be safe to say my kids carry the recessive gene for brown eyes or hazel eyes. Even though they inherited the dominant allele for blue from both parents.
