An unusual case is described in which a man was accused of the paternity of a child, and an expert reported him to be type RhzRh1, the mother as type Rh1rh and the child as type Rh2rh, thus excluding paternity. In repeat blood tests, the author confirmed the typing results on the putative father and the mother, but showed the child to be type Rhzrh instead of type Rh2rh, so that paternity was not excluded. Instead, the presence in both putative father and child of the rare gene RZ (or ry) could be considered circumstantial evidence that the accused man actually was the father. It is pointed out that the error could easily have been due to the mistaken use of anti-rhi serum in place of anti-rh′ serum. Such an error would be more apt to occur with a worker using the fallacious C-D-E notations, because the tacit assumption implicit in those notations that each agglutinogen has but a single corresponding antibody (and blood factor) would render unthinkable the concept of more than one kind of anti-rh′ (anti-C) reagent.
