Chromosome 19 has a blue/green gene. Chromosome 15 has a brown/blue gene. The genetics of eye color are more complex than realized previously, and more than one gene is involved in determining eye color.

What is the difference between a gene and trait?
Trait is a characteristic like: tall, short, black eyes, blue eyes Trait is determine by the genes: your gene is a little section on chromosome. A gene that control 1 trait usually have 2 alleles, for ex: Blue eyes is : Bb (b or B are the alleles make up the gene that determine the trait.) hope this help for whoever confuse!
Can you give me an example of a simple sentence using the word dominant trait?
Blue eyes are a dominant trait.
Are green eyes dominant over brown eyes?
In most cases, no. If your parents give you a blue eye trait and a brown eye trait, you will most likely have brown eyes. However, there are many different alleles that factor into your eye color. That is why there are so many shades of eye color, such as blue, green, gray, brown, hazel, blue-green, etc... So, you may not always get pure blue or brown eyes, you may get a mix of both.
Is eye color an example of a trait?
False, eye color is an example of a trait. Hair color, nose shape, and curly and not curly hair are all also traits. Anything that can possibly be unique and distinguishable is a trait, so yes, eye color is a trait.
Is it possible to have green eyes if your parents have dark brown and blue eyes?
It is possible because they can always carry the trait of having green eyes. You will most likely have blue eyes, though, because blue is a dominant 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.

Genetically speaking blue eyes are?
Blue eyes - a recessive trait.
Why are your eyes blue?
Blue eyes are a recessive trait that is passed down by the parents to the child through their genes.
What genotype does a baby need to be a blue eyed boy?
The blue eyed boy needs the X and Y chromosome to be a boy, and since blue eyes is a recessive trait, it must receive the blue eyed gene from both the mother and the father.
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.
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.
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.
In human brown eyes (B) is a dominant trait and blue (b) , recessive trait?
Not my answer
What is the bigger population brown eyes or blue eyes?
brown eyes because of the genetic trait
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 it rare to have a dad with blue and a mom with brown and yours be blue?
Blue eyes are known to be a recessive genetic trait, or a trait that is not commonly found. Because your dad has blue eyes, it means that he also has the "blue eye" trait in his gene. An offspring (you in this case) can get that same "blue eye" trait as well as traits from your mom. Although it is more common to get other dominant trait, such as brown, you got blue. I wouldn't say it is rare but it is definitely uncommon.
