Blue is a recessive trait, meaning both parents need both alleles to code for blue. So the baby will have blue eyes, because there aren't alleles for any other color in these genes.

Baby will also have blue.
Basic genetics problems usually say that B brown is dominant to b blue. In that case, bb x bb parents will have bb kids.
It's more likely that eye color is controlled by at least two pairs of genes. The four alleles for these two pairs of genes must all say "blue" for the person's eyes to be blue. So two blue eyed parents would have the genotypes aabb and aabb. Their kids would all be expected to be aabb also.

blue probaly but if the grandparents have green eyes the baby could have hazel,gray or green eyes.if the parents and grandparents both sides have blue or green or hazel eyes there is no chance the baby would have brown eyes or black eyes unless the true father did.

Blue. If mom and dad both have blue then they only carry the blue genes (recessive)... although there's more to it than that if you *really* want to get in depth...

this is a genetic question. it may blue, black or brown. becouse blue eye is resesive allel. if the grandparent (from both - mum and dad) have other than blue coloured aye, the kid may show other than blue eye colour.
