recessive allele, the member of a pair of alleles that lacks the ability to express itself in the presence of a dominant allele at the same locus.It is expressed only in the homozygous state. Compare dominant allele.See also autosomal-recessive inheritance.he member of a pair of alleles that lacks the ability to express itself in the presence of a dominant allele at the same locus. It is expressed only in the homozygous state. Compare dominant allele. See also autosomal-recessive inheritance.
For an example, if we consider the dominant allele as (A) and recessive allele as (a), then in the case of homozygous, the two alleles can be written as AA, and it can be written as Aa, in the case of heterozygous.In both situations, the dominant allele can express its phenotype over recessive allele.ecessive Allele. From the two alleles, the weaker one is known as recessive allele. This recessive allele is expressed only in the case of homozygous. In the case of heterozygous, the dominant allele masks the phenotype of the recessive allele.
