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.
If both parents have brown eyes, it means they both carry the dominant brown eye color gene. However, if their first child has blue eyes, it indicates that both parents carry the recessive blue eye color gene. The chances of their second child having blue eyes would be 25%, as both parents would have to pass on the recessive gene for blue eyes.
Yes, it is possible for a child to have brown eyes if their parents' eyes are hazel. Hazel eyes are a combination of brown and green eye pigments, so if the child inherits the brown pigment from both parents, they would likely have brown eyes. Eye color is determined by a combination of genetic factors from both parents.
It is possible for a child to have blue eyes if both parents are carriers of the recessive blue eye gene. Blue eyes are a recessive trait, so if both parents carry this gene, there is a chance their child could inherit blue eyes.
Not always, as eye color is determined by multiple genes. It is possible for two blue-eyed parents to have a brown-eyed child if both parents carry the gene for brown eyes. This genetic combination can produce a child with brown eyes even though both parents have blue eyes.
Yes, it is possible for two parents with brown eyes to have a child with blue eyes if both parents carry a recessive gene for blue eyes. If each parent passes on this recessive gene to the child, then the child can have blue eyes. Eye color inheritance is a complex genetic trait involving multiple genes.
That the trait for blue eyes was recessive in both parents.
Your wife had an affair; simple.
If both parents have brown eyes, it means they both carry the dominant brown eye color gene. However, if their first child has blue eyes, it indicates that both parents carry the recessive blue eye color gene. The chances of their second child having blue eyes would be 25%, as both parents would have to pass on the recessive gene for blue eyes.
Yes, it is possible for a child to have brown eyes if their parents' eyes are hazel. Hazel eyes are a combination of brown and green eye pigments, so if the child inherits the brown pigment from both parents, they would likely have brown eyes. Eye color is determined by a combination of genetic factors from both parents.
Yes, two parents with brown eyes can have a child with blue eyes if both parents carry a recessive blue eye gene. Blue eyes are a recessive trait, so both parents must carry at least one copy of the blue eye gene for it to be expressed in their child.
The gene for blue eyes is recessive.
It is possible for a child to have blue eyes if both parents are carriers of the recessive blue eye gene. Blue eyes are a recessive trait, so if both parents carry this gene, there is a chance their child could inherit blue eyes.
Not always, as eye color is determined by multiple genes. It is possible for two blue-eyed parents to have a brown-eyed child if both parents carry the gene for brown eyes. This genetic combination can produce a child with brown eyes even though both parents have blue eyes.
Yes, it is possible for two parents with brown eyes to have a child with blue eyes if both parents carry a recessive gene for blue eyes. If each parent passes on this recessive gene to the child, then the child can have blue eyes. Eye color inheritance is a complex genetic trait involving multiple genes.
Yes, it's possible for a child to have blue eyes if both parents carry the recessive gene for blue eyes. Eye color is determined by multiple genes, so even if both parents have brown or green eyes, they can still carry the gene for blue eyes and pass it on to their child.
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.
Yes, it is possible for two brown-eyed parents to have a blue-eyed child if both parents carry a recessive blue eye gene and pass it on to their child. Eye color is determined by multiple genes, so the presence of blue eyes can sometimes skip generations.
