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?
What else can I help you with?
How is it possible for two brown-eyed parents to have a blue-eyed child?
It is possible for two brown-eyed parents to have a blue-eyed child if both parents carry a recessive gene for blue eyes. When these recessive genes are passed on to the child, they can combine to produce the trait of blue eyes, even if the parents themselves have brown eyes.
Mendelian inheritance is it possible for two brown eyed parents to have a blue eyed child?
Yes, because blue is recessive
Can two brown eyed parents produce a blue eyed child if the mothers parent is the only one with blue eyes?
It is genetically possible for two brown-eyed parents to have a blue-eyed child if both parents carry a recessive blue eye gene. If the mother's parent has blue eyes, it means she carries the blue eye gene, and this gene could be passed on to the child.
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.
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 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, it is possible for a blue-eyed male and a brown-eyed female to have a brown-eyed child. Eye color is a polygenic trait, meaning it is influenced by multiple genes. Both parents can carry genes for brown eyes, and if those genes are passed on to the child, they can have brown eyes even if neither parent has brown eyes.
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 to blue eyed parents have brown eyed children?
Yes, it is possible for two blue-eyed parents to have children with brown eyes if both parents are carriers of the brown eye gene. Eye color is determined by multiple genes, so variations can occur in offspring even if both parents have the same eye color.
Can two hybrid blue eyed people have a brown eyed baby?
Yes, it is possible for two hybrid blue-eyed parents to have a brown-eyed child if both parents carry a recessive brown-eyed gene. Eye color is determined by multiple genes, so the outcome can vary.
Will two blue eyed parents have a blue eyed baby?
blue eye genes are recessive so a person must receive blue eye genes from both parents, meaning they don't have any other eye color gene to give their child except blue. Blue is recessive not only to brown, but also to green eyes so if there was one gene from either side then the person's eyes would not be blue.
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.
Can a blue eyed mom and blue eyed dad have a brown eyed baby?
It is not possible for two blue-eyed parents to have a brown-eyed biological child. Eye color is determined by genetics, with brown being a dominant trait and blue being a recessive trait. If both parents have blue eyes, it is very likely that their child will also have blue eyes.
