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.
Yes, because if a blue-eyed man is BB or Bb, meaning the B is blue-eyed and dominant, and the b is brown-eyed and recessive, marries a woman who is bb, or has brown-eyes, the children could be either all blue-eyed if the man was BB, or 50% are blue-eyed if the man is Bb.
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.
Check your question it doesn't make sense
either blue eyes or green eyes. ===
A green eyed mother and a blue eyed father can have a child with blue eyes.
I have green eyes my hubs has hazel colour, neither green or blue!, we have 3 children eldest is bright blue male second is green eyed girl and youngest is brown eyed male,(the only one who looks like mum, who has green eyes)
Yes, as long as one of their Grandparents/ Great Grandparents has blue eyes. If both pairs of Grandparents have brown eyes then it is VERY unlikely :)
Yes. The woman can be heterogeneous non-blue. That means she carries a blue eyed gene and a non-blue eyed gene. The blue eyed is normally recessive so he carries both blue eye genes and doesn't carry a non-blue gene.If two blue eyed parents have a child then the child will be blue eyed.
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!
you cannot have a blue eyed boy. unless there is someone in your family that has blue eyes. the brown and green would be either a recessive or dominent trait. traits don't mix together to create different things. like brown and green. brown and green don't even mix to make blue
yes. if the dad has 1 recessive blue gene and 1 dominant brown gene then he can either pass on the blue gene or the brown gene.
yes it can be true but sometimes not

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.
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.
Yes, absolutely. Hazel eyes is the combination of the blue and brown eye color gene. For instance, a blue eyed mother and brown eyed father could have a hazel eye colored child. So that means all hazel eyed children can have a brown eyed child because they carry the brown eyed gene in their DNA from their father, in this case.
either blue eyes or green eyes. ===
