recessive

 [re-ses´iv]
1. tending to recede.
2. in genetics, incapable of expression unless the responsible allele is carried by both members of a set of homologous chromosomes. See also recessive gene.
3. an allele or trait that has this characteristic.

re·ces·sive

(rē-ses'iv),
1. Drawing away; receding.
2. In genetics, denoting a trait due to a particular allele or alleles at a single locus that does not manifest itself unless mutant alleles are present on both homologous chromosomes of a pair.

recessive

(rĭ-sĕs′ĭv)
adj.
1. Tending to go backward or recede.
2.
a. Genetics Of, relating to, or designating an allele that does not produce a characteristic effect when present with a dominant allele.
b. Of or relating to a trait that is expressed only when the determining allele is present in the homozygous condition.
n. Genetics
1. A recessive allele or trait.
2. An organism having a recessive trait.

re·ces′sive·ly adv.

recessive

Genetics A genetic trait that is not phenotypically expressed in a heterozygous or partially heterozygous cell, but rather only in a homozygous or hemizygous state. See Phenotype, Trait. Cf Dominant.

re·ces·sive

(rĕ-ses'iv)
1. Drawing away; receding.
2. genetics Denoting a trait due to a particular allele that does not manifest itself in the presence of other alleles that generate traits dominant to it.

recessive

Pertaining to an alternative form of a gene (ALLELE) that produces an effect only when carried by both members of the pair of homologous chromosomes (only when HOMOZYGOUS). People with heterozygous alleles for a condition are called carriers. A recessive gene has no effect in the presence of a DOMINANT allele either because of its inactivity or because of the absence of a product.

Recessive

Refers to an inherited characteristic or trait that is expressed only when two copies of the gene responsible for it are present.

re·ces·sive

(rĕ-ses'iv)
Drawing away; receding.
