Family tree indicating genotypes and phenotypes for individual 1.

Rh phenotype and genotype (italics) are shown. Propositus is indicated by an arrow. DAR is in linkage with ceAR(indicated as DAR-ceAR), whereas ceEK is not associated with any RHD gene (indicated as no D-ceEK). Propositus and individual II-6 have the same molecular background and the same rare phenotype (RH:−18).
