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 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?
It should be a dominant allele--a dominant allele's trait will be expressed over the recessive allele's trait.
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 single gene trait?
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
What is e difference between a dominate and recessive allele?
The answer is that The difference is that dominant dominates, and recessive is dominated.
What allele does affect the trait in a heterozygote?
The recessive allele.
What allele whose trait only shows up when no dominant allele is present?
Such a trait is called a recessive trait.
How do you know a homozygous trait from a heterozygous trait?
A homozygous trait is controlled by only one kind of allele, while a heterozygous trait is controlled by multiple allele types.
