when both alleles of a trait are expressed at the same time
The condition in which two alleles in a heterozygous organism are both expressed, so the phenotype has characteristics of both of the phenotypes of individuals homozygous for either allele. Blood type (A, B, AB, O) is an example of codominance.
Refers to two alleles that each contribute to the phenotype of a heterozygote.
describing alternative alleles of a gene that are both equally manifested in the individual.
Where two alleles at a locus are expressed.
Two different alleles of the same gene that are both expressed, for example A and B alleles of the ABO blood group system, or red and white color alleles of a flower resulting in pink coloration.

Genes that, when present together, will both influence the appearances of the same Trait.
two genes that are neither dominant or recessive; neither masks the other, as in the case of red geraniums crossed with white geraniums yielding pink geraniums.
designating genes when both alleles of a pair are fully expressed in the heterozygote odon: the nucleotide triplet in messenger RNA that specifies the amino acid to be inserted in a specific position in the forming polypeptide during translation
Two alleles that are both seen in one individual. Example: AB blood type (see dominant and recessive).
