group system in human blood transfusion. Rhesus blood group system: The Rh blood group is one of the most complex blood groups known in humans.it has become second in importance only to the ABO blood group in the field of transfusion medicine.It was discovered by Landsteiner and Weiner in 1940. they research with the rhesus monkeys on human blood chemistry led to the discovery of the Rh factor. Rh status will be listed as negative (-) or positive (+). the Rh negative (Rh-) gene is also masked by the presence of a Rh positive (Rh+) genotype.
