Elimination Tool:
The gene I controls the human ABO blood types. Alleles IA, IB, and I are present. Six distinct genotypes are possible due to the three distinct alleles. However, since each of us receives one blood type allele from our biological mother and one from our biological father, a single person has two ABO blood type alleles. Therefore, B is the right response.
