Recessive is the name of a gene in genetics. It is a gene that does not convey its commands when paired with a central gene. It is an allele that is expressed only when available in the homozygous or hemizygous condition. The phenotypic expression of a recessive gene is masked by a dominant allele. It produces its affect only in a situation where both copies present are identical. A recessive gene attribute will be passed on to offspring's with only a 1 in 4 chance. In genetics these genes are indicate with lower case letters.

Technically, the expression "recessive gene" is imprecise coz it is not the gene that is recessive but the phenotype (or trait). Recessive genetic disorder takes place only when both parents are carriers and each contributes an allele to the embryo. Thus there must be two copies of the allele.
