A trait is generally expressed phenotypically. An allele is one of a pair alleles at the same locus...often referred to as a gene. An allele is present whether expressed or not.
A single gene locus will have two alleles in an individual, but there may be more than
2 alleles for this locus in the population.
General human blood groups are an example of this with A,B, O as the primary alleles and several other less common ones...(like M) present in the population.

What is the difference between a gene allele Chromosome and trait?
Alleles are alternate versions of genes that code for certain phenotypes, or traits. The traits of an individual are a result of the interaction between their genotype (alleles) and the environment.
What is the difference between the dominant and recessive allele for a trait?
An individual must have 2 recessive alleles in order for a trait to show up. One must only have 1 dominant allele in order for a trait to occur.
What is the difference between an allele and a genotype?
An allele is a specific version of a gene, while a genotype refers to the combination of alleles that an individual has for a particular trait. In simpler terms, an allele is like a variation of a gene, and a genotype is the specific genetic makeup of an individual.
What allele whose trait only shows up when no dominant allele is present?
Such a trait is called a recessive trait.
What carrier of a trait controlled by a allele does not express the trait?
A carrier of a trait controlled by a recessive allele possesses one copy of the recessive allele and one copy of the dominant allele. This means that they do not express the trait associated with the recessive allele because the dominant allele masks its effect. However, the carrier can pass the recessive allele to their offspring, who may express the trait if they inherit two copies of the recessive allele.
In a heterozygote the allele that does not affect the trait?
The allele that does not affect the trait in a heterozygote is known as the recessive allele. This allele is masked by the dominant allele, which determines the observable trait. However, the recessive allele can still be passed on to offspring if both parents are carriers.
What is member of a gene pair that determines a specific trait is?
an allele
How does an allele trait in an organism?
An allele causes a trait by either being dominant orrecessive or example, allele A will occur over allele a because it is dominant.
What is the difference between dominant and recessive alleles for specific traits?
Dominant is an allele that will always be expressed in a heterozygous individual. Recessive on other hand are traits that will only be expressed in a homozygous condition. Organisms receive one allele for each trait from each parent, thus you have two alleles for each trait.
What is difference between a dominant trait and a recessive trait?
A recessive trait is a trait that is not shown or expressed physically but is retained within the persons genes, whereas a dominant trait is a trait which opresses the recessive trait and is prodominantly shown or expressed physically. For example it is possible for two red-haired parents, both with recessive dark haired genes, to have a dark haired child. they must both have the recessive gene or the dominant gene of red - hair will be expressed in the child
An allele that is dominated or cover up by another allele is called what?
An allele that is dominated or covered up by another allele is called a recessive allele. This means that the trait associated with the recessive allele is only expressed when an individual carries two copies of that allele.
What is e difference between a dominate and recessive allele?
The answer is that The difference is that dominant dominates, and recessive is dominated.
