One variant phenotype of this group is known as the "weak D". One nomenclature for identifying it was developed by Fisher and Race, which uses the letters c, d, and e to mark its alleles, while an older nomenclature is named for Weiner. Phillip Levine connected this set of factors to a condition that is currently prevented by the drug Rhogam, known as erythroblastosis fetalis or hemolytic disease of the newborn, in which a mother produces antibodies to this factor. Originally discovered in a namesake species of monkey, for 10 points, name this blood group that is usually notated by a plus or m
