Genetics of the Rh-Hr locus in humans

An analysis is attempted to throw more light on the inheritance of rhesus factor in humans and the Fisher-Race and Wiener's concepts are respectively evaluated. It is claimed that the Rh-Hr locus is not comprised of the recombination of C, D, E, c and e genes, much less the help of the auxiliary (d) which merely appears to be a conventional approach derived from an even principle of recombination for a polyhybrid cross. As for Wiener's rare or common mutants of Rh-Hr in humans and the emergence of different agglutinogens like a sort of genetic proliferation, no such parallel of inheritance has yet been found in experimental plants or animals. Probably the scarcity of certain genotypes is due to the rare chance of fertilization or embryonic development due to incompatibility between certain mutants of Rh-Hr genes, similar to ABO-Rh incompatibility.
