If both parents have blue eyes is it possible for them to have a baby with brown eyes?

Yes.
Brown eye gene = B
Blue eye gene = b
Each person has two copies of the eye color gene in their genome, one inherited from each parent. Now if both parents only carry the gene for brown eyes, BB and BB, then their child will receive one B from each parent, ending up as BB. The same works for blue eyes, if that's the only gene both parents carry, bb and bb. Each parents gives on b to the child, who ends up as bb.
If you have one parent who only has the gene for brown eyes, BB, and one parent who only has the gene for blue eyes, bb, then all the children will have brown eyes. Example: One parent gives a B, the other gives a b. Bb = brown eyes. Here's why: When you have two alleles (coding sequences) from genes that are at odds with each other, one version will override the the other. When dealing with eye color, B always dominates b. But these children now carry the b gene in them, and could pass it down to their own children. Some of them, depending on the other parent, could end up with blue eyes.
If one parent is Bb, and the other is bb, then each time they have a child, there is a 50% chance it will have blue eyes. Example: First parent is Bb, second parent is bb, then their children will end up as either Bb, bb, Bb, bb. If both parents carry the genes for brown eyes and blue eyes, then each time they have a child, there is a 25% chance it will have blue eyes. Example: First parent is Bb, second parent is Bb, then their children will end up as either BB, Bb, Bb, bb.

Can two brown eyed parents make a blue eyed baby?
It is uncommon for a baby to be born with brown eyes. Almost all babies have blue eyes because the iris has not yet made brown pigment (called melanin) that colors the iris. It is, however, common for babies to have blue eyes at 2 weeks. Usually, the iris doesn't make enough melanin until about 3 years of age. In other words, genetically, it is very well possible to have a baby that eventually will become brown eyed, or even green eyed, even a very rare combination of brown and blue on each individual eye is possible. Whilst the text so far is all correct, it is only uncommon but not unheard of for two blue eyed parents to have a brown eyed baby from birth. It is a fascinating subject. read more at : related link down below.
Is it possible to have green eyes if your parents have dark brown and blue eyes?
It is possible because they can always carry the trait of having green eyes. You will most likely have blue eyes, though, because blue is a dominant color. :)
The parents of Tim have brown eyes but Tim has blue eyes so How is this possible?
Tim's parents both have the recessive trait for blue eyes but their brown eye traits are the dominant ones that show. Time must have by chance gotten both the recessive genes from his parents and no brown eye genes thus his blue eyes go without the brown taking over.
What colour eyes and hair will a baby have if the mother has dark brown hair hazel eyes the father has light brown hair and blue eyes?
Blue eyes are recessive to brown eyes. So if the mother is heterozygous for brown eyes then it is possible for the child to have blue eyes. However if the mother is homozygous for brown eyes than the child will have brown eyes. Since both parents are brunettes, the child will definitely have brown hair as well.
What color eyes and hair will a baby most likely have if the father has blonde hair blue eyes and the mother has brown hair green eyes?
The Baby will almost definitely have brown hair and brown eyes. If the father has a blonde haired gene or blue eyed gene (if one of his parents or grand parents had blonde hair and blue eyes) there is a possibility the baby will have blonde hair and blue eyes (one in four chance).
Is it possible for blue eyed parents to have a brown eyed baby?
Yes, buy only if the parents are heterozygous for the trait and if the trait is dominant.
My brother has baby blue eyes and his girlfriend has light green eyes there baby was born with brown eyes Is this possible We dont think its his child and none of our family has brown eyes?
Of course the baby can have brown eyes!! Only 2 blue eyed people can have a blue eyed baby, any other eye colour is possible when 2 parents have different colour eyes.
Can a two blue eyed parents have a brown eyed baby?
maybe
Can a baby have blue eyes if father has brown eyes and mother has blue eyes?
It is very possible to have a blue eye child if both parents have different eye colors. It's also possible to have kids that have different eye colors.
Biracial baby with blue eyes parents brown eyes?
It means the parents carried the gene for blue eyes as a recessive gene.
Can a baby have blue eyes if both parents have brown eyes and grandparents on one side have blue and brown and on the other side have green and brown?
yes, although the likely hood chance is that it will have brown eyes as both of the parents do.
What are the specifics about the genetics for two blue eyed people to have a brown eyed baby?
It is impossible for a baby to have brown eyes if both of his parents have blue eyes since the brown eye gene is more dominant.
Is true that you can have a baby with blue eyes if both of the parents have browns eyes?
It is very unlikely, and I would say no but I do not know for sure. I do know that a baby is born with blue eyes if both parents have blue eyes, and that brown eyes are a dominant gene, soo.. curiously enough, blue is a rare eye colour. The order of common to rare: brown Hazel blue and blue-gray green violet (yes it is possible, Elizabeth Taylor had violet eyes)
Can both parents have blue eyes and have a brown eyed baby?
No... Brown eyes are an dominating gene. If none off the parents have brown eyes none of them have the brown eye gene to give the child.
IF a mother has green eyes and the father has blue could a baby have brown eyes?
Yes. Brown is the domanent color. Look at his parents and her parents eyes. what colors do they have?
Can two brown eyed parents have a blue eyed baby even if no one in the family is blue eyed?
I believe so, if both the parents have recessive alleles for blue eyes.
Is is possible for two brown eyed parents to have a blue eyed baby if three of the grandparents are brown eyed?
Yes, because brown eyes are the dominate trait, blue eyes might be the "hidden trait." one of the grandparents have the hidden trait, they passed it onto the parent, and the the blue eyes trait became dominate in the child.
