A person with Type AB blood displays both A- and B-antigens and has the genotype I A I B … WebIn some traits, however, alleles may be codominant —i.e., neither acts as dominant or recessive. An example is the human ABO blood group system; persons with type AB blood have one allele for A and one for B. (Persons with neither are type O.) Most traits are determined by more than two alleles.

WebThere are three alleles for the ABO gene: A, B, and O. 5. The genes for ABO blood type and Rh blood type exhibit independent assortment because they are located on different chromosomes. The ABO gene is located on chromosome 9, while the Rh gene is located on chromosome 1. WebA and B are both dominant to O, but neither is dominant to the other.
