Scheme of the possible infection rules according to RhD blood types and ABO ones.
Full line connection indicated the possibility of infection, Wij = 1, while dotted connection its impossibility. In the RhD infection system, individuals of the same group can infect each other, people with the RhD- group can transmit the infection to people with RhD+ one, but not viceversa. The scenario of the ABO system is similar although richer. For instance, the O type can infect the A type, while the opposite is not possible.
