Rh(0) or D, -D- and the blocking patterns. A genetic (template) explanation.

By the use of the gene template it will be shown that D appears at two different sites on the Rh locus, and that the locus cannot simply be DCE - or a similar one. Further, -D- does not appear to be a super Rh(0) as described by Wiener. Finally, a simple explanation is offered for the action of incomplete (blocking) and agglutinating antibodies.
