Several genes in humans in addition to the ABO gene (I ) give rise to recognizable antigens on the surface of red blood cells. The MN and Rh genes are two examples. The Rh locus can contain either a positive or a negative allele, with positive being dominant to negative. M and N are codominant alleles of the MN gene. Suppose a child's blood type is B MN Rh(neg). The mother's blood type is O N Rh(neg). Check all of the blood types below that the father could have. (Assume no involvement of the Bombay phenotype; everyone is HH). A. O M Rh- O M Rh -
B. B MN Rh+ B MN Rh+
C. A M Rh+ A M Rh+
D. O MN Rh+ O MN Rh+
E. B MM Rh+ B MM Rh+
F. B NN Rh-
