When a person possesses two different alleles at the same locus, and both alleles are expressed in the phenotype, this is called Codominance.
Alleles
According to leading textbooks on genetics and evolution, an allele is a variant of the same sequence of nucleotides at the same location on a lengthy DNA molecule. "A locus is the chromosomal or genomic site of a gene or other genetic element, and alleles are variant DNA sequences at a locus." The majority of alleles observed have little or no effect on the function of the gene product for which they code. Various alleles can, however, result in variable observable phenotypic features, such as different colouring. Gregor Mendel's discovery that the white and purple blossom hues of pea plants were caused by a single gene with two alleles is an example of this.
