Abstract:
Two genetic polymorphisms of salivary proteins were found by polyacrylamide gel electrophoresis among inbred strains of rats. Both proteins (RSP-1 and RSP-2) were inherited as a single autosomal trait. The loci were designated as Rsp-1 (rat salivary protein-1) and Rsp-2. Rsp-1 had two codominant alleles (Rsp-1a, Rsp-1b), and Rsp-2 had two alleles (Rsp-2a, and Rsp-2b); Rsp-2a was dominant over Rsp-2b. The Rsp-1 locus is not linked with the linkage groups (LGs) I, II, IV, V and the LGs containing Acp-2 and Pg-1. The Rsp-2 is not linked with the LGs I, II, V, X and the LGs containing Amy-1, Es-6 and Pg-1.
