Scientific definitions for codominant

codominant
[ kō-dŏmə-nənt ]

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.
