codominance

(kō-dŏm′ə-nəns)
n.
A heterozygous condition in which both alleles at a gene locus are fully expressed in the phenotype.

codominance

the relationship between two different ALLELES of a gene in the HETEROZYGOTE, producing a PHENOTYPE containing both parental forms of the character. For example, allele A of the ABO blood group is codominant to allele B, so that an individual with both alleles (A/B) produces both A and B antigens. Compare INCOMPLETE DOMINANCE. See DOMINANCE (1).

A bay scallop sample (CR) obtained from a hatchery and used for mtDNA RFLP analysis by Blake and Graves (1995) also had codominant haplotypes, suggesting that the codominance of H2 and H3 we observed resulted from supplementation with hatchery bay scallops.
(2006) divided our white fir sites into white fir (n 5 5), mixed-conifer (n 5 3), and mixed-fir (n 5 1, in addition to the three sites herein treated as mixed-fir), based on levels of codominance of white and red fir.
Codominance (ko-dohm-i-nahns) When different alleles are located at one loci, but neither is dominant to the other.

No codominance was observed and albino offspring were distinguished from wild-type mice on the day of birth, as found in albino meadow voles, Microtus pennsylvanicus (Brewer et al., 1993).
Twenty-one of the 128 RFLP markers were dominant and the rest exhibited codominance. The SSR markers were all developed from soybean and identified by the prefix "Sat_," "Satt," or "Sct_" (Cregan et al., 1999).
The report describes a mathematical modelling activity of a natural phenomenon (transmission of hereditary characters in a codominance case) using the concept of model as a theoretical instrument.
Most AFLPs are dominant markers, although codominance was apparent for some peaks (about seven loci), where A/A and A/a genotypes were distinguishable by dosage or peak height (Fig.
Yucca may be in codominance with Larrea, Coleogyne, or Juniperus (Turner 1982).
