It is the dominant gene in you. The same gene can be dominant or recessive, depending on the parents.
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.

Why is there a greater chance of getting a dominant trait rather than a recessive trait?
A dominant trait occurs when either both alleles are dominant or one allele is dominant and the other is recessive. This is because a dominant allele overpowers a recessive allele. In order to have a recessive trait both alleles must be recessive.
Are blue eyes dominant over green eyes?
No. They are both recessive meaning that both parents must have the gene for either blue or green.
What if your friend has blue eyes her genes contain one allele for blue eyes and one allele for brown eyes which allele is recessive how do you know?
The brown allele is recessive. Think: Blue = B, and brown = b Your friend is Bb, or heterozygous for the gene. In heterozygotes, the expressed phenotype is the dominant gene, which in this case, apparently, is blue. Thus, because your friend does not have brown eyes, the brown allele must be recessive.
Can a brown eyed man and a green eyed woman have a blue eyed son?
Brown is dominant and Green is somewhere in the middle. There are possibilities that this may occur but without the genes then it is hard to tell. To get blue eyes both parents would need blue eyed recessive genes and the kid would have to receive both those recessive genes which is very rare. In this case blue eyes is not a sex-linked gene so its possible the the male and female with have a female with blue eyes. Most likely the child will have brown eyes though. This is because if the son does get the recessive from the mother, but gets the dominant from the father, the dominant will overpower the recessive and the son will just be another blue eye gene carrier and himself have brown eyes.
Can a green eyed man and brown eyed woman have a green eyed daughter?
Yes. Blue eyes are a recessive genetic trait, which means that a brown- or green-eyed person can still carry a gene for blue eyes. In this case, the blue-eyed gene is recessive, or subordinate, to the green- or brown-eyed gene. To be blue-eyed, an individual must have a recessive blue-eyed gene from both its mother and father.
How can both your parents have brown eyes and you have blue?
It means they carried the gene for blue eyes as a recessive gene. If they both gave you this gene, then you will come out with blue eyes.
What is a sentence with the word recessive?
The color of one's eyes are supposedly determined by a recessive gene.
Biracial baby with blue eyes parents brown eyes?
It means the parents carried the gene for blue eyes as a recessive gene.
Why are my daughters eyes blue while mine and her fathers are brown?
You both carried the gene for blue eyes as a recessive gene.

A dominant trait occurs when either both alleles are dominant or one allele is dominant and the other is recessive. This is because a dominant allele overpowers a recessive allele. In order to have a recessive trait both alleles must be recessive.
Your wife and you both have brown eyes your son has blue can this be right?
Yes. You both carry the gene for blue eyes as a recessive gene.
Are blue eyes a dominant trait?
no they are a recessive gene. You would receive a blue gene from each parent
If eyes color of mother is blue and eyes color of father is black how did the child get black color?
Black eye color is a recessive trait meaning that for someone to have it both the mother and father would have to pass off the gene for Black eyes. Since the dominant gene always prevails over the recessive and one of the parents had blue eyes, this means that the parent with black eyes had both recessive genes for black eyes and therefor passed on the recessive gene. The other parent with the Blue eyes must have both genes blue and black, but since blue is considered to be dominant over black the blue, they have blue eyes, but passed on the recessive black eye gene. B - Blue Eye Gene (Dominant) b - Black Eye Gene (recessive) Mother - Bb (Blue Eyes) Father - bb (Black Eyes) Child - bb (Black Eyes)
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.
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.
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.
What is the color of the baby eyes if the mother have the recessive gene for blue and the father has blue eyes?
I assume you mean the mother has a dominant allele for some other color. Father is homozygous recessive for blue. Dominant allele + recessive blue X recessive blue + recessive blue The baby has a 50% chance of blue eyes and a 50% chance of getting the dominant colored eyes.
