Protein polymorphisms and their genetic control in the red-backed vole, Clethrionomys rufocanus bedfordiae

Twenty enzymatic and non-enzymatic proteins in a wild population of red-backed voles, Cletrionomys rufocanus bedfordiae, were investigated by electrophoresis. Seven enzymatic and non-enzymatic protein systems were found to be polymorphic. Breeding data indicated that the mode of inheritance of the enzyme systems ME-1, ME-2, GPD and EST were consistent with a Mendelian law. Two systems, 6 PGD and SOD, were estimated to be genetically controlled from the electrophoretic patterns and mother-offspring comparison of phenotypes. In the Tf system two new additional phenotypes were observed, but their inheritance could not be elucidated. Gene frequencies at seven loci were also investigated in 88 animals. There was no significant deviation from Hardy-Weinberg equilibrium.
