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.
Is is possible for two brown eyed parents to have a blue eyed baby if three of the grandparents are brown eyed?
Yes, because brown eyes are the dominate trait, blue eyes might be the "hidden trait." one of the grandparents have the hidden trait, they passed it onto the parent, and the the blue eyes trait became dominate in the child.
How can this be possible where the couple has brown eyes and the child can have blue eyes?
Blue eyes are a recessive trait, while brown eyes are dominant. If both parents are heterozygous for brown eyes, it means they both carry the recessive trait for blue eyes, and so there is a 25% chance their offspring will be blue-eyed.
The parents of Tim have brown eyes but Tim has blue eyes so How is this possible?
Tim's parents both have the recessive trait for blue eyes but their brown eye traits are the dominant ones that show. Time must have by chance gotten both the recessive genes from his parents and no brown eye genes thus his blue eyes go without the brown taking over.
Is it possible for blue eyed parents to have a brown eyed baby?
Yes, buy only if the parents are heterozygous for the trait and if the trait is dominant.
Why are your eyes blue?
Blue eyes are a recessive trait that is passed down by the parents to the child through their genes.
Could two blue-eyed parents have a brown-eyed child?
GeneticsYes, it's possible for a pair of blue-eyed parents to have a brown-eyed offspring. It all depends on each parent's genotype, and which trait comes from the dominant or recessive allele.
Can a man who has brown eyes and whose both parents have brown eyes produce a blue eyed child if his wife has blue eyes?
yes, if the man with brown eyes had a recessive blue trait. his parents would have to both have the recessive trait as well. the parents with dominate brown (B) with recessive blue (b) eye color traits would create a chart of possible outcomes for their child: B b B bb Bb b Bb bb if the man came out Bb (dominate brown with recessive blue) and had a wife with bb (the only way to have blue eyes is to have two recessive blue traits because if a pair of traits has a Brown then the brwn color will automatically dominate over the blue) the man and the wife will make an eye color chart like this: B b b Bb bb b Bb bb there is a 50/50 chance the child will have blue eyes. if the child has the bb trait then it will have blue eyes.
Can someone with brown eyes and one with green eyes have a blue eyed child?
It is possible for a child with a brown-eyed parent and a green-eyed parent to have blue eyes if there is the trait for blue eyes in the child's genetics. Such as a grandparent with blue eyes.
If both parents are a positive can the child be a negative?
yes. because of recessive genes. recesive genes are traits that will not be shown if the dominant gene for that trait is present. every person has at least two alleles(forms of traits) for each trait that is shown. One you see and the other you may not. For example, two parents may have brown eyes, but if they have a child that has blue eyes then you know that the parents must have carried the recessive gene. this is possible because the brown eye allele is dominant and the blue eye allele is recessive. Even though you did not see the blue eye trait in either of the parents it was still present.
Why do you have blue eyes when your dad has brown eyes?
Blue eyes is a recessive trait. Both parents could be blue gene carriers.
What if a gene skips a child can that gene be given to there kid?
A person can only pass on genes that he/she has inherited from his/her parents. You may be talking about a situation in which a recessive gene is not expressed in a child because it inherited a dominant allele as well, and is heterozygous for that trait. If that child then has his/her own child, the recessive trait could be expressed in the children of that child, if the other parent also carries the recessive allele.Example: One parent has brown eyes, the other has blue eyes. Their child inherited a brown eye allele and a blue eye allele, and has brown eyes, but is heterozygous. This child then has a child with another brown-eyed person, and their offspring has blue eyes, even though both parents have brown eyes. It just so happens that both of these parents are heterozygous for brown eyes, so they both carry the recessive blue-eyed allele which they each passed on to their blue-eyed offspring. So, this makes it look like the blue-eyed allele skipped a generation, but in reality it was always there, but not always expressed.
