The inactive allele is invisible in an organism while an expressed allele is the dominant allele and therefor is the phenotype.
Epistasis occurs when one gene masks the expression of another gene, while dominance is when one allele of a gene is expressed over another allele. In epistasis, the interaction between genes affects the phenotype, while in dominance, one allele is dominant and determines the phenotype.
An allele that is always expressed when it is present is the dominant allele.
In a situation where both a dominant and recessive allele are present in a gene pair, the dominant allele will be expressed phenotypically. The presence of a dominant allele overrides the expression of the recessive allele.
A dominant allele will mask the prsence of a recssive allele
In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed
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.
The allele not expressed is referred to as a recessiveallele.
Yes, a recessive allele will be expressed if there is no dominant allele present in the genotype. This is because in the absence of a dominant allele, the recessive allele has the opportunity to be expressed in the phenotype.
The answer is that The difference is that dominant dominates, and recessive is dominated.
Yes, a recessive allele needs to be paired with another recessive allele in order to be expressed. This is because recessive alleles are only expressed when an individual has two copies of the recessive allele, one from each parent. If an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele will be expressed.
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.
An allele that is always expressed when it is present is the dominant allele.

Epistasis occurs when one gene masks the expression of another gene, while dominance is when one allele of a gene is expressed over another allele. In epistasis, the interaction between genes affects the phenotype, while in dominance, one allele is dominant and determines the phenotype.
Dominant allele as opposed to recessive allele.
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.
A dominant allele will mask the expression of a recessive allele when they are present together in an organism. The dominant allele will be expressed, while the recessive allele will not be visibly expressed in the organism's phenotype.
