It has co-dominance. In co-dominance, neither phenotype is dominant. Instead, the individual expresses both phenotypes. The most important example is in Landsteiner blood types. The gene for blood types has three alleles: A, B, and O. O type is recessive to both A and B. When a person has both A and B, they have type AB blood.
Another example involves Short Horn cattle. If a homozygous bull and homozygous cow mate (one being red and the other white), then the calves produced will be roan-colored, with a mix of red and white hairs.

A great example of this is blood type. The three alleles are A, B, and O. A and B code for a protein on the surface of red blood cells, and O is the lack of either the A or B protein. They are also examples of codominance, since a person can have AB type blood. (If a person has AO or BO, they do have the protein created by the A or B allele.)
