Therefore, an individual with type AB blood can receive blood from any group, but can only donate blood to another group AB individual. 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. WebJul 24, 2013 · In genetics-speak, these alleles are dominant over the recessive alleles. In the case of the ABO gene, A and B are dominant over O.
