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
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 happened with my dad. His dad had blue eyes and his mom has brown eyes and he ended up with hazel.
The baby could have either blue or green eyes.
If the baby gets a brown eye gene from one parent and a blue eye gene from the other parent, the child will likely have brown eyes because brown is dominant over blue. Or if the brown eyed parent has a blue recessive gene and the baby gets it then that child will have 2 blue eye genes and will have blue eyes. Of course there could be other recessive genes of other colors so the child could have hazel or green too. This is my basic understanding of how it works.
it may brown, that's how it is sometimes
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!
Blue. Her mom and dad has brown and green eyes respectively.
red hair
He will have extra dark black eyes like donkeys and pack mules Different Person~Hey! that was rude! Really, the child can have any shade of brown or blue. I hope I helped! ---- The baby will have Brown eyes because Brown is the stronger color! Hope it helps!!xxx
Yes, if there is brown eyes in the family, then yes, it is possible.
Yes, they can - and it happens more commonly than you'd think.
