Abstract

Juneja, R. K., van de Weghe, A. and Gahne, B. 1984. Genetic polymorphism of serum postalbumin (Po) and pretransferrin (Prt) in the laboratory rabbit. —Hereditas 100:11–15. Lund, Sweden. ISSN 0018–0661. Received March 14, 1983 A new genetic polymorphism of a rabbit serum protein, designated postalbumin (Po) was detected by two-dimensional agarose gel (pH 8.6)-polyacrylamide gel (pH 9.0) electrophoresis. Family data indicated that the three different Po phenotypes observed were controlled by two codominant, autosomal alleles PoF and Pos). Considerable polymorphism of Po was observed in White of Dendennonde breed, while the New Zealand White rabbits showed only the Po S phenotype. The earlier reported rabbit serum protein alleles, PaF and PaS (post-albumin) and Prt+ (pretransferrin) were shown to belong to the same genetic system and their new nomenclature is proposed to be PrtD, PrtF and PrtS, respectively. The three Prt alleles with considerable frequencies were observed in each of the two breeds studied.
