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?
Can a parent with blue eyes and brown eyes produce a child with blue eyes?
Yes, it is possible for a parent with blue eyes and brown eyes to have a child with blue eyes if both parents carry the gene for blue eyes. Eye color is determined by multiple genes, so it is possible for a child to inherit the blue eye color gene from both parents.
Is it possible for a person with brown-eyed parents and no recessive blue eye gene to have a blue-eyed child if their partner has blue eyes?
Yes, it is possible. If one parent has blue eyes, they must carry two blue eye genes (bb) and can only pass on a blue eye gene to their offspring. If the other parent does not carry any blue eye genes, their child has a chance of inheriting a blue eye gene from the blue-eyed parent. This would result in the child having blue eyes.
Can a blue eyed parent and a brown eyed parent have blue eyed children?
The blue eyed parents may have heterozygous genotypes with the dominant gene and recessive gene for blue and brown eyes respectively. During segregation of gametes, their is a likelihood that their child may inherit the recessive genes from both parents. Consequently, their child will have brown eyes.
Can a blue eyed man and a brown eyed woman make a blue eyed kid?
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.
How would you create an individual who will definetely have blue eyes?
To ensure an individual has blue eyes, both parents must carry at least one copy of the gene for blue eyes. This means each parent could have two blue eye genes or one blue and one non-blue gene. If both parents pass on the blue eye gene, the individual will have blue eyes.
Can a parent with blue eyes and a parent with green eyes have a very blue eyed baby?
Yes, if they have a dominate blue gene.
Are blue eyes a dominant trait?
no they are a recessive gene. You would receive a blue gene from each parent
Can a parent with blue eyes and brown eyes produce a child with blue eyes?
Yes, it is possible for a parent with blue eyes and brown eyes to have a child with blue eyes if both parents carry the gene for blue eyes. Eye color is determined by multiple genes, so it is possible for a child to inherit the blue eye color gene from both parents.
Is it possible for a person with brown-eyed parents and no recessive blue eye gene to have a blue-eyed child if their partner has blue eyes?
Yes, it is possible. If one parent has blue eyes, they must carry two blue eye genes (bb) and can only pass on a blue eye gene to their offspring. If the other parent does not carry any blue eye genes, their child has a chance of inheriting a blue eye gene from the blue-eyed parent. This would result in the child having blue eyes.
Can a blue eyed parent and a brown eyed parent have blue eyed children?
The blue eyed parents may have heterozygous genotypes with the dominant gene and recessive gene for blue and brown eyes respectively. During segregation of gametes, their is a likelihood that their child may inherit the recessive genes from both parents. Consequently, their child will have brown eyes.
Is it possible for a blue eyed individual to have a parent with brown eyes?
yes the blue eyes gene could have been passed down from another family mnember, not just by a parent.

What color would your eyes be if your parents have different eye color?
if your parents have different color eyes: if eyes are not brown, no brown gene lets say one green other brown. green parent may have green/blue gene. brown parent may have brown/green gene. your eyes might be blue. 1/4 chance of it.
How would you create an individual who will definetely have blue eyes?
To ensure an individual has blue eyes, both parents must carry at least one copy of the gene for blue eyes. This means each parent could have two blue eye genes or one blue and one non-blue gene. If both parents pass on the blue eye gene, the individual will have blue eyes.
If your first born baby has blue eyes will all other have the same eye color?
If you have blue eyes and the other parent has blue eyes then all you children will have blue eyes. Blue eyes are a recessive gene and two recessive genes will dominate.
It is possible for a filipino brown eyed and a American blue eyed have a blue eyed baby?
It is highly unlikely, as the gene for brown eyes is dominant over the gene for blue eyes, and it's unlike the Filipino parent is carrying the blue gene. The baby will carry the gene for blue eyes, and if it's own spouse is blue-eyed, each of its children has a 50% chance of being blue-eyed.
If blue eyes are caused by a recessive gene why then are there any children with blue eyes anymore Shouldn't all children now have brown eyes Explain why this isn't the case?
Blue eyes being recessive just means that someone must have 2 blue-eye genes to have blue eyes. If they had one brown-eye gene and one blue-eye gene, they would have brown eyes but their kid(s) might have blue eyes, depending on the genetics of the other parent.
