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.

∙ 13y agoYes, traits are determined by genotypes. and someone can be heterozygous or hold two traits, the trait they show, is called the dominant trait. the other is called the recessive.
In order for it to work though both parents have to be heterozygous (or have both traits)
there is about a 1/4 chance though!

∙ 14y agoIt is possible if both brown eyed parents have a recessive blue eye allele. In that case, there is a 25% chance that their offspring will express blue eyes.

∙ 12y agoAbsolutely. My mother has blue eyes, my father green eyes, my older sister inherited my father's green eyes and I have blue ones like my mom.

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.
Are there more brown eyed people in the world than blue eyed?
NO. People with blue eyes do NOT have the brown eyed gene, if they did they themselves would have developed brown eyes instead of their blue as it is dominant. So two blue eyed parents can only pass the blue gene to their offspring.
If father and mother both have blue eyes is it possible to have a baby with brown eyes?
There is a chance the baby will have blue eyes but only 1:3 chance. You carry 2 blue eye genes. If he carry's 2 brown genes then all your baby's will have brown eyes. But, if he carry's 1 brown gene and 1 blue gene then the chances of blue:brown eyes are 1:3. Hope this helps :)
Brown eyes are dominant over blue eyes in humans The genetic makeup of blue-eyed children who have brown-eyed parents must be?
B (dominant) is for brown and b (recessive) is for blue. If both parents have brown eyes, for them to have a blue-eyed child their genotypes (the combination of b's) must both be Bb, because they both need to provide a little b (to have blue eyes you must be double recessive (bb)). This is worked out using a Punnett Square. (example: https://mcglynn-bioreview4.wikispaces.com/file/view/basicpunnetsquare.jpg)
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.
Can a two blue eyed parents have a brown eyed baby?
maybe
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.
Can a brown eyed dad and a blue eyed mom make a blue eyed baby?
yes, only 2 blue eyed people can only have a blue eyed baby, this will not change ever! where as 2 brown eyed people can also have a blue eyed baby, but for 2 blue eyed people to have a brown eyed baby is impossible!
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 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.
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.
Can brown eyed man and a blue eyed woman have blue eyed baby?
Yes!
Can a green eyed man and a blue eyed woman have a brown eyed kid?
It depends on the genes because some genes from the parents might not get passed on making the baby have brown eyes
Can a blue eyed and brown eyed produce a green eyed baby?
Yes, I have a son that has green eyes. I have blue, his father has brown.
Can a brown eyed man and a brown eyed woman have a blue eyed baby?
Yes, because your genes have both dominant and recessive traits, so you may have 1 blue and 1 brown and your wife may have 1 blue and 1 brown and (and this is gross simplification) when your genes combine if even one of your brown traits gets passed onto the child it will have brown eyes.
What is the likelihood of having a brown eyed baby if both mother and father are blond and blue eyed?
Zero. Blue eyes come from a recessive gene (brown eyes come from a dominant gene). So two blue-eyed parents have only blue-eye genes in them. Therefore, they can pass only blue-eye genes to their baby.
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.
