Genetic linkage data for the Dombrock blood group locus relative to chromosome 1 and chromosome 4 loci

Summary Odds favouring Do: PGD linkage (ž+ 3.56 at θ= 0.23) based on the average antilod are 920:20≃46:1. If Do is located on chromosome 1 it lies distal to PGD and recombination between PGD and Do occurs more frequently in male than in female meioses. Our data do not support Do:GC linkage.
