A genealogia adiante revela grupos sanguíneos do sistema ABO. A análise da genealogia sugere que a) o indivíduo II-2 pertence ao grupo sanguíneo A.

b) a probabilidade de o indivíduo II-4 ser do grupo 0 (zero) é 100%.

c) o indivíduo II-1 não apresenta os aglutinogênios A nem B, antígenos que são glicoproteínas.

d) o alelo IA é dominante em relação ao alelo IB e os indivíduos ii não possuem as aglutininas anti-A e anti-B.

e) o casal I-1 x I-2 pode vir a ter filhos dos quatro grupos sanguíneos do sistema ABO.
