An individual has the following Rh phenotype: D+C+E+c+e+. Using the Fisher-Race terminology, what is their most likely Rh genotype?

DCE/Dce
dce/dce
DCe/DcE
DCe/dcE

DCe/DcE

This Rh group terminology is based on the theory that antigens of the system are produced by three closely linked alleles and each gene is responsible for producing an antigen on the RBC surface.
