- Ecology. being one of two or more species that are equally dominant in a biotic community: a forest in which oak and hickory are codominant.
- Genetics. of or relating to two different alleles that are fully expressed in a heterozygous individual.

Historical Examples of codominant
Grasses are dominant in the ground cover, and Sphaeralcea coccinea (globe mallow) is codominant.
Quercus gambelii and Amelanchier utahensis were the codominant shrubs.
The codominant shrubs in the understory of this zone are Amelanchier utahensis, Artemisia nova and Purshia tridentata.
The dominant and codominant plants in the overstory (trees or shrubs) were noted at each station.
- genetics (of genes) having both alleles expressed equally in the phenotype of the organism
- Of or relating to an equal degree of dominance of two genes, both being expressed in the phenotype of the individual.
- Relating to two alleles of a gene pair in a heterozygote that are both fully expressed. When alleles for both white and red are present in a carnation, for example, the result is a pink carnation since both alleles are codominant.
- Being one of two or more of the most common or important species in an ecological community. Like a dominant species, codominant species often influence the presence and type of other species in the community.
