In genetics, a trait that will appear in the offspring if one of the parents contributes it. * In humans, dark hair is a dominant trait; if one parent contributes a http://www.answers.com/topic/gene for dark hair and the other contributes a gene for light hair, the child will have dark hair.

The difference between a dominate and a recessive trait is?
A dominant trait is expressed when an individual has one or two copies of the dominant allele, while a recessive trait is only expressed when an individual has two copies of the recessive allele. Dominant traits mask the expression of recessive traits in heterozygous individuals.
Is heterozygeous dominant or reccesive?
Heterozygous means that it carries both dominant and recessive traits (as opposed to homozygous which carries only one) - the dominant trait is the one which is expressed (phenotype). A heterozygous trait can be expressed as Rr - "R" the dominant trait and "r" the recessive trait.
What did mendel call the trait that always showed up?
Mendel called the trait that was always expressed the dominant trait.
A genetic trait expressed in a person who has only one copy of the gene associated with the trait?
This is known as a dominant trait. Dominant traits require only one copy of the gene to be expressed in an individual. The presence of one dominant allele is sufficient to display the trait, even if the individual also carries a different allele for the same gene.
What is a domainit trait?
A dominant trait is a genetic trait that is expressed when an individual has one copy of the dominant allele. In a pair of alleles (one from each parent), the dominant allele will mask the expression of the recessive allele.
In a hybrid individual the trait that is covered and not expressed is the what trait?
recessive
When a trait is not expressed when paired with a dominant allele is the definiton of?
The trait that is not expressed when paired with a dominant allele is known as a recessive trait. It is masked by the dominant trait in individuals carrying both alleles.
A trait that appears or is expressed in the f1 generation is what?
A trait that appears or is expressed in the F1 generation is considered dominant. Dominant traits will manifest themselves in the offspring when at least one parent carries the dominant allele for that trait.
What is a trait that is expressed even if only one gene for that form of the trait is inherited?
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.
What is the term for an expressed allele?
dominant trait
What is a dominate trait?
Dominant trait is a genetics term. A dominant trait is one which will be expressed if one of the parents has the gene for that trait. A recessive trait is one that will be expressed only if both parents carry the trait.
What trait is is expressed when two diffrent genes for the same trait are present?
A dominant trait is expressed when two different genes for the same trait are present.
Not expressed when the dominant form of a trait is present?
Recessive traits are not expressed when the dominant form is present. This is because the dominant allele masks the expression of the recessive allele in the heterozygous condition. Only when an individual has two copies of the recessive allele will the recessive trait be expressed.
What trait is expressed when two different genes for the same trait are present?
dominant
When do you see a dominate trait?
When the allele that codes for the dominant trait is expressed in the genome.
When neither allele is dominant (they are both expressed)?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
What trait is the one that is expressed in a hybrid organism?
dominant
