The major histocompatibility complex of Rhesus monkeys.: XIV. A family study of DR and other RhLA-linked cell membrane antigens*

Abstract
The segregation of B cell specific determinants was studied in a large number of rhesus families. As expected, on the basis of results of a recent population study, the 8 serologically defined DR antigens segregated as alleles of a single locus within RhLA. Two or 3 antigens not controlled by DR remained candidates for a 2nd Ia series closely linked to DR. The 162 identifiable haplotypes provided interesting information regarding positive associations among antigens of 2, 3 or even 4 sets of RhLA loci. A new series of antigens closely linked to the RhLA-A locus was postulated. Data obtained from 8 recombinant offspring permitted a better definition of the mapping position of all known loci of RhLA.
