A protein.
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.
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.

An allele that is always expressed when it is present is the dominant allele.
Dominant allele as opposed to recessive allele.
A dominant allele located on an autosome will be expressed phenotypically in the individual, meaning it will be visible in the physical characteristics of the organism. This dominant allele will mask the effects of any recessive allele at the same locus.
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.
An expressed allele is actively used to produce a specific protein or trait in an organism, while an inactive allele is not being actively used or expressed due to various factors such as mutations or epigenetic modifications. Inactive alleles may still be present in an individual's genetic makeup but are not contributing to the phenotype.
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.
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.
The term applied to the trait that is expressed in regardless of the second allele is dominant. In contrast, the term recessive refers to a trait that is expressed when the second allele is identical.
