What are odds of 2 blue eyed parents having a brown eyed child?

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.

∙ 13y agoThis is not an easy question to answer if possible at all.
The early ideas of eye color and genetics is obsolete. Parents may produce a child of any eye color combination. Until we know more about genetics and inherited traits, it is at best a spin of the wheel.

Can a blue eyed male with both his parents having blue eyes marries a brown eyed female with her mother having blue eyes and her father having brown eyes could they have a brown eyed child?
Yes. Brown is dominant for eye color.
What if your eyes are blue and your girlfriends eyes are brown Will your child have blue eyes or brown eyes?
You have a better chance of brown, because brown is dominant. If one of your girfriend's parents have blue eyes you have a The your girlfriend is a carrier of the recessive blue eyes gene and there is a 50% chance that your child will have blue eyes. If neither of her parents had blue eyes but one of their parents had blue eyes there is a 25% chance your child will have blue eyes. But statistics do not generally apply perfectly to real life, because life is fairly random. So it's better to say your chances SHOULD be 50% of having a child with blue eyes if one of your girlfriends parents have blue eyes, and your chances SHOULD be 25% etc.....
Can a child get brown eyes if parents' eyes are hazel?
a child with parents eyes that are blue and grey are more likely to get blue eyes. But it is not impossible that a child with those parents cant get brown eyes. My parents have brown and blue eyes and i got grey. It isn't impossible but quite rare.
If parents have Blue and Brown eyes what will the child have?
any color
If a child has blue eyes and both her parents have brown eyes what does that tell you about the trait for blue eyes?
That the trait for blue eyes was recessive in both parents.
What is blue child?
Blue childeren are FROM both PARENTS HAVING negative blood hence blue blood.
How come both of a child's parents have brown eyes but the child can has blue eyes?
Your wife had an affair; simple.
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.
What eye color will be the child's eye color if the mom is green and the dads eye color is blue?
The green eye and the blue eye are the same gene, so is black and brown. The child's eyes would have to be green or blue because both parents onlt have blue genes. If both parents have brown eyes there is still a chance the child's eyes could come out blue, but only if one of the parents have a hidden blue gene. But is both parents have blue eyes this means all their genes are blue and the child will 100% have blue eyes.
If a child has blue eyes and both parents have brown eyess what does that tell you about the trait?
The gene for blue eyes is recessive.
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.
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.
