Normally, no, they can't. This is because the allele for blue eyes is recessive, whereas the allele for brown eyes is dominant. Since both parents have blue eyes they are both homozygous recessive ie. carrying only blue eye alleles. Since both parents only carry the blue eye allele they can only pass blue eye allele on to their children.
BUT, there is a fractionally small possibility that a spontaneous mutation could occur in the eye colour gene in one of their gametes that would change an allele for blue eyes into an allele for brown eyes. If this gamete then takes part in fertilization then the resultant child will have brown eyes because they are now heterozygous (one blue eye allele, one brown eye allele) with the brown eye allele being dominant.
ALSO, it could happen if one of your prospective parents is a chimera - a person who has effectively two genotypes because their cells originate from two different zygotes. If one of your prospective grandparents had brown eyes and gave a brown eye allele to one of this chimera's genotypes (the one responsible for forming gametes) while the other genotype of this chimera (the one responsible for forming eyes) had only blue eyed alleles, this blue eyed person could form gametes with brown eye alleles and hence have a brown eyed baby. Human chimeras are extremely rare, but an example would be Lydia Fairchild.
Isn't genetics wonderful?

Can to blue eyed parents have brown eyed children?
no they cannot because if you have blue eyes, your alleles are bb, and so... bb and bb have no B, and therefore, with no dominant gene, there cannot be a brown eyed child.
Mendelian inheritance is it possible for two brown eyed parents to have a blue eyed child?
Yes, because blue is recessive
Could two blue-eyed parents have a brown-eyed child?
GeneticsYes, it's possible for a pair of blue-eyed parents to have a brown-eyed offspring. It all depends on each parent's genotype, and which trait comes from the dominant or recessive allele.
Can 2 brown eyed parents produce a green eyed child?
Well, both of my parents had brown eyes. Out of 11 kids 3 had brown and the rest of us had blue.Come to think of it, the mailman and the milkman had blue eyes.
Can two brown eyes parents produce a blue eyes child?
I don't think two brown eyed parents produce a blue eyed child, but a brown eyed parent and a blue eyed parent can produce a child with blue eyes. Brown eyes are not always dominate.Two brown-eyed parents CAN produce a blue-eyed child if BOTH carry the recessive gene for blue eyes. Recessive means it can hide, but is still present and ready to be carried on to a future generation. Brown eyes ARE dominant. If you carry the gene for brown eyes, your eyes are brown. This does not mean you can't also carry the recessive gene for blue/green eyes.
Can a blue eyed male with both his parents having blue eyes marries a brown eyed female with her mother having blue eyes and her father having brown eyes could they have a brown eyed child?
Yes. Brown is dominant for eye color.
Can a blue eyed man and a brown eyed woman make a blue eyed kid?
Theoretically, a blue eyed man and a blue eyed woman cannot produce a brown-eyed child. The reason is that neither parent carries the brown-eyed gene. If the father or mother did carry the brown-eyed gene, the eyes/irises of that parent would be brown. The gene for brown is dominant over the gene for blue. However, two brown eyed parents can produce a blue eyed child. In that case, each parent with brown eyes must carry the gene for blue - the parents' eyes are brown because the brown gene is dominant over the blue gene. However, if the child inherits a blue gene from both brown eyed parents, the result will be blue eyes although both parents have brown eyes. In the case of one parent with brown eyes and one parent with blue eyes, there is a possibility that the parent with brown eyes possesses the non-dominant blue gene. If the child inherits the blue gene from that brown eyed parent, the child's eyes will be blue since the gene from the other parent with blue eyes will be blue. There is a condition known as heterochromia iridis where one eye is brown and one eye is blue. This condition is usually pathological on a neurogenic or inflammatory basis with the abnormality usually being in the lighter/ blue eye. Acquired heterochromia iridis that develops in an adult may suggest a melanoma of the iris in the brown eye.
Is it possible for a person with brown-eyed parents and no recessive blue eye gene to have a blue-eyed child if their partner has blue eyes?
Yes, the child probably inherited the blue eyes from the person with blue eyes.
Can blue-eyed parents make a brown eyed child?
Yes, it is possible, but there must be two (recessive) brown eye genes or at least one dominant one, that were dormant in the parents.
Eye color can a child have blue eyes from brown and green eyed parents?
yes, people with brown eyes can carry the blue eye gene, so two brown-or-green-eyed people who both carry the blue eye gene have a 25% chance chance of a blue eyed child (with each birth).
Can a brown eyed momand dad have a blue eyed child?
if one of ur second level parents (grandma...) has brown eyes, yes, it is a dominant gen
Can a brown-eyed father and a blue-eyed mother have a blue-eyed child?
yes, but rarely.
