The hemopexin locus: Its assignment to Linkage Group I in the laboratory rabbit (Oryctolagus cuniculus) and evidence for a fourth allele*

The hemopexin locus phenotypes were determined for 450 animals with polyacrylamide gel electrophoresis, and the presence of a fourth allele at this locus was revealed. Of the 19 mating types segregating at this locus, 17 demonstrated segregation ratios consistent with the hypothesis of a four allele, codominant, autosomal system. Studies of three of our largest inbreeding lines indicated that fixation at this locus has occurred in two of them. Linkage studies showed that the Hx locus is located between the color locus, c, and the Hq blood group locus; therefore it is assigned to Linkage Group I of the rabbit.
