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.

recessive allele

or

recessive gene

an ALLELE that only shows its effect in the PHENOTYPE when present in a HOMOZYGOTE. When paired with a dominant allele the effect of the recessive allele is hidden. see RECESSIVE CHARACTER.

Dominant alleles at the B locus (B) correspond to black hair and skin color, and recessive alleles at the B.
Recessive alleles, even when they are disadvantageous, can initially increase in a population as a result of drift, because they are "under the radar" of natural selection in heterozygotes and, while they are rare, it is unlikely that random mating among the dominant phenotype will result in recessive phenotypes in the offspring.
Expected numbers were calculated under Mendelian segregation, assuming that the bluish type was controlled by a recessive allele at a single locus.
These results suggest that the bluish and greenish shell color variant types are controlled by recessive allele (b) and dominant allele (G) at a single locus, and the genotype of parental individuals in the pair-cross A are estimated as G/b.
An additional advantage of this method is that it easily allows for recombination mapping with recessive alleles in trans as well as in cis.
