We present new genetic evidence obtained from population studies on Finns and from the studies on Finnish blood donors as well as their selected families using an antibody that defines a novel high‐incidence Rh antigen MAR. Anti‐MAR antibody shows an antithetical relationship to both anti‐C w and anti‐C x . The Rh antigens C w (RH8) and, more strikingly, C x (RH9) have each an exceptionally high frequency in Finns. Our studies on their genetic relationship indicate that the three antigens C w , C x and MAR behave as if being determined by alleles of the same Rh sub‐system. Furthermore, we conclude that this sub‐system manifests an inheritance pattern that is distinct from but analogous to that of the two well‐known allelic sub‐systems of C/c and E/e antigens.
