Abstract As the chimpanzee R-C-E-F blood group system appears to be the chimpanzee counterpart of the human Rhesus (RH) system, we have tried to determine whether chimpanzee Rh-like genes encode R-C-E-F-related proteins. Chimpanzee genomic DNA, digested by any of eight endonucleases and hybridized with three Rh exon-specific probes, exhibits a high degree of polymorphism. Analysis of DNA from unrelated individuals of different R-C-E-F types revealed that the presence of some restriction fragments is correlated with particular R-C-E-F types. The cosegregation of these fragments with R-C-E-F haplotypes was confirmed by family studies. Oligonucleotides complementary to regions flanking human exons were used as PCR primers on chimpanzee DNA; the resulting amplified fragments were identical in size to their human counterparts. Moreover, the nucleotide sequences of the fragments present a high degree of similarity to the corresponding human regions.
