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.
What else can I help you with?
If my husband eyes are green and my eyes are brown what color would be my baby eye color?
Brown eyes are always more predominant. My son has brown eyes like myself. His fathers eyes were blue. Baby's eyes are always blue until they are about 6 months old, then they begin to change to their 'real' colour. The colour of your baby's eyes will depend on whether one of your parents has eye colour other than brown, in which case your baby might have non-brown eyes (50:50 chance). If both your parents had brown eyes, then you can *only* pass on brown genes, which (as above said) are predominant, and therefore your babies can (usually) only have brown eyes. Hope this is understandable.
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.
If a man had black hair and blue eyes and the woman had blond hair blue eyes can the child come out with brown eyes blond hair if the grandmother had brown eyes?
Blue eyes are a recessive trait. If at least one of the parents had a blue/hazel eyes with a mixture of blue and brown, then the couple's offspring could have brown eyes. If both parents had solid blue eyes, neither would have the dominant brown gene to pass to the baby, and it would have blue eyes, regardless of the grandmother's eye color.
What color eyes and hair will a baby boy most likely have if the father has blonde hair blue eyes and the mother has brown hair green eyes?
The baby boy is most likely to have brown hair and blue or green eyes. Brown hair is a dominant trait, so it is more likely to be expressed. Blue eyes are recessive, but it is possible for the baby to inherit them if both parents carry the gene. Green eyes are a combination of blue and brown pigments, so the baby may inherit either blue or green eyes from the parents.
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 brown eyed man and a blue eyed woman have blue eyed baby?
Yes!
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.
