If someone has a dominant trait such as brown hair and his or her mate has a recessive trait that is brown hair can the offspring have brown hair?

I think you've mis-asked this question, since you've used "brown hair" in both portions of the question. If you mean, if one person has brown hair and another has blond hair, will their children have blond or brown hair? The answer is it's highly likely that the children will have brown hair - brown hair is a dominant gene - but there is a possibility that the child will have blond hair, since the way the genes combine is not always the same. If it were always predictable, all children from the same parents would be the same, like clones of each other; and they're not.

Are green eyes dominant or recessive?
yes they are recessive
What happens when an allele is dominate or recessive?
Well, a dominant allele carries dominant traits from parents to offspring. An example of a dominant trait is brown hair and brown eyes because these traits are most likely to show up on a human than a recessive allele. A recessive allele may carry a recessive trait from parents to offspring such as blonde hair and blue eyes, these are uncommon because they are recessive traits.
In order for a child to inherit a recessive trait both parents must be carriers of the recessive gene?
No. A recessive gene can be inherited from one parent, a dominant from another, or two alike dominants. (No such thing as two alike recessive, the gene with the furthest back dominant gene. Say a blonde little girl has a blonde hybrid mother and a brown hybrid father. She ended up getting brown recessive. Since both of her parents were hybrid, she only had a recessive hair color gene from one parent.
What is allele masked by the dominant allele?
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.
What are the difference between dominant and recessive genes?
Dominant genes will cover up recessive genes. Take a simplified version of eye color for example. Brown is dominant and blue is recessive. Someone might have the allele for both brown and blue, but their eyes will be brown because of the dominent brown gene. If there are two parents that carry the recessive gene, neither will be blue eyed, but they will have a chance of having a blue eyed child if both pass on the recessive gene.
Brown eyes are dominant Cross a homozygous brown with a recessive blue What color eyes will the offspring have?
all brown the chances of brown eyes both parents have to have blueeyes for blue eyes to become dominant but its still possible no matter what for blue or brown
Is chromosomal mutation dominant or recessive?
They can be both. Wikipedia provides small descriptions of some of the different types of mutation
Are green eyes dominant or recessive?
yes they are recessive
What percent of the offspring will most likely have brown fur?
If brown fur is a dominant trait in the offspring's parents, then approximately 75% of the offspring will most likely have brown fur. This is because there is a 75% chance that each offspring will inherit at least one dominant brown fur gene from the parents.
When a brown guinea pig was crossed with a white guinea pig her offspring were all brown why?
This is probably the result of the brown genes being dominant and the white genes being recessive. this is correct.
What happens when an allele is dominate or recessive?

A brown mouse is repeatedly mated with a white mouse all the offspring are brown if two of the offspring are mated what fraction of the F2 mice will be brown?
75% or 3/4. The two F1 (offspring) mice have a genotype Bb, and express the dominant (brown) trait. When they mate, 1/4 will be BB (homozygous dominant - brown), 2/4 will be Bb (heterozygous - brown), and 1/4 will be bb (homozygous recessive - white).
Are brown eyes dominant or recessive?
Brown eyes are dominant. That's why more people have brown eyes then hazel or blue or green.
What happens when a dominant and recessive allele are both present?
The resulting offspring will have the dominant trait. It depends on if the dominant is hetero or homo...if it was homozygous then your offspring will have a hetozygous trait showing the dominant trait (to clear this up if you are confused lets say we are talking about brown eyes(BB-dominant) vs blue eyes(bb-recessive)--a homozygous would give you a brown eyed child with Bb and but if the person is heterozygous Bb and gets with a recessive you have a chance of getting Bb or bb giving you a possibility of a brown or blue eyed child)...wow i just made that way more confusing than it had to be
Compare and contrast dominant and recessive?
In genetics, each organism will typically have 2 alleles for each trait. For a trait such as hair color, you might have an allele for red hair from your dad and an allele for brown hair from your mom. The trait for brown hair happens to be dominant to the trait for red hair so you would show the allele for brown hair. (In other words, you would have brown hair.)
Are green eyes dominant?
With brown eyes, they are recessive.
Is brown skin dominant or recessive?
Dominant - everything is dominant apart from diseases such as malaria, cystic fibrosis
