In genetics, denoting an equal degree of dominance of two genes, both being expressed in the phenotype of the individual; for example, genes A and B of the ABO blood group are codominant; individuals with both are type AB.

In Botryllus, the primary fusion/rejection response is controlled by a single, highly polymorphic locus, in which the sharing of one, or both, codominant alleles leads to fusion, and the absence of a shared allele leads to nonfusion or cytotoxic rejection (Oka and Watanabe 1957; Sabbadin 1962; Scofield et al.
In Caucasian populations, three distinct types of electrophoretic patterns were recognized referred to as [Ak.sub.1] l [Ak.sub.1] 2-1 and [Ak.sub.1] 2 corresponding to the presence of two codominant alleles, [Ak.sub.1.sup.*]1 and [Ak.sub.1.sup.*]2 at an autosomal locus.
Each parent exhibited a unique protein band the other lacked, but the two bands segregated in the RILs as codominant alleles at a single locus that was assigned the marker name MatSdPro.
There are three common codominant alleles, designated [epsilon]2, [epsilon]3, and [epsilon]4 (2).
The biosynthesis of each protein isoform is under the control of three independent codominant alleles, [member of]2, [member of]3, and [member of]4, located at a single Apo E gene locus on chromosome 19g13.
Thirty-six of 68 DNA clones and 39 of 72 DNA clones detected segregating RFLP loci with codominant alleles in [S.sub.1] progenies of MAD and WIF, respectively.
