Science Dictionary
codominant   (kō-dŏm'ə-nənt)  Pronunciation Key 

  1. 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.

  2. 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.
