In humans, there are four blood types: A, B, AB and O. The blood type is dependent on the type of antigen present on red blood cells (A, B, or both). Individuals that lack the antigens are type O. This is the recessive trait. A and B are both equally dominant and both antigens can be expressed, which results in AB blood type. This is an example o

Solution
It seems like you didn't finish your question. However, based on the information you provided, it seems like you're describing an example of codominance. In genetics, codominance is a phenomenon where two versions (alleles) of a gene are expressed simultaneously in a heterozygote. In the case of the AB blood type, the A and B alleles are both expressed, hence it's an example of codominance.

Blood type in humans is determined by the type of carbohydrate present on the red blood cells.A red blood cell may have carbohydrate A (IA), carbohydrate B (IB), or no carbohydrate (i).Carbohydrate A and carbohydrate B are codominant to each other and both A and B arecompletely dominant to the allele for no carbohydrate.
Individuals with O type blood: A. Have circulating antibodies against both the A and B blood group antigens. B. Do not have antibodies against either A, B or O blood group antigens. C. Are susceptible to infection because they lack circulating antibodies. D. Can safely receive A, B, AB and O type donor blood.
