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.
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.
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.
You cant have red eyes... but the baby would most likely get blue eyes or brown (If the dd had brown, then the baby would have brown)
His favourite colour was blue they predict
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)
Yes!
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.
there is no way to be certain until the baby is born, but my mum has dark brown eyes, my father blue, and i also have blue eyes.
red hair
It depends, but most probably brown - because it is a more dominant colour. - x S.
no. there is no such colour as brown, just blue.
brown
Pink and also baby blue and violet and red and yellow and white and green and turquoise and purple and brown and cyan and orange and indigo but mostly baby blue
you gotta mix red with blue to get brown
its sooo gotta be green his favorite colour is acctualy red(:
grey
brown green=blue
