Glossary Term Codominant
Definition One of a series of terms applied to the phenotypic effect of a particular allele in reference to another allele (usually the standard wild-type allele) with respect to a given trait. An allele "a" is said to be codominant with respect to the wild-type allele "A" if the A/a heterozygote fully expresses both of the phenotypes associated with the a/a and A/A homozygotes. An example of codominance is the ABO blood type antigens in humans, where AA individuals are type A, BB individuals are type B, and AB individuals are type AB.
