What is the most probable Rh genotype of a baby born to a mother with red cell phenotype D+C+E-c-e+ and anti-c, and a father with D+C+E-c+e+?

To determine the most probable Rh genotype of the baby based on the red cell phenotypes and the presence of specific antibodies in the mother, we must first analyze the genotypes of the parents and their Rh factor.

The mother's phenotype is D+C+E-c-e+ (indicating she has the D antigen and is positive for C and E antigens, but negative for the c antigen and positive for e). The anti-c antibody suggests that she likely inherited the c antigen as part of her Rh genotype from one of her parents but expresses the absence of it in her own cells. This hints at the possibility of her genotype being either R1r (where she inherits R1 which includes the D, C, E antigens from one side and r that has the c, e antigens from the other) or R1R2 (leading to C and E but c may not be present due to lack of one c allele).

The father’s phenotype is D+C+E-c+e+ (also expressing D, C, and E and is positive for c and e). With him being c+ and e+, we see that he must carry the c allele.

Taking this information into account, the child is likely to inherit an Rh
