Definitions for "CODOMINANT ALLELES"
Genes wherein both members of an allelic pair are fully expressed.
Alleles whose phenotypes are both expressed in the heterozygote. Example: The AB blood group is due to a single gene which produces a protein that is found on the surface of the red blood cells. The A and B alleles of this gene produce antigenically distinct forms of this protein which can be recognized by antibodies specific to each form. A person who inherits the A allele from one parent and the B allele from the other will express both forms of the protein, so their red cells will react with both the A and B antibodies. We say they have type AB blood.
two alleles that have different effects that are distinguishable in a heterozygous individual (e.g. AB blood groups)
