摘要：
Protein polymorphism has been studied by means of starch gel electrophoresis of tissue extracts in three population samples of Graomys griseoflavus collected at different sites in central-west Argentina. Individuals from two of the samples had chromosomal number 2n = 42 and those from the other sample, 2n = 38, 37 or 36. A total of 28 loci were analyzed. High levels of variability were observed in three samples (P ranging between 0.46 and 0.66; H-c from 0.160 to 0.188). Genetic distance values between populations with different chromosome numbers were 0.088 and 0.093. Tests in the laboratory showed the existence of post-zygotic reproductive isolation between animals with 2n = 42 and those with 2n = 38, 37 or 36.
