Abstract
The karyotypes of Cynomys leucurus (2N = 50) and C. gunnisoni (2N = 40) are described and compared with the previously published karyotype of C. ludovicianus (2N = 50). Sera from the three taxa are also compared electrophoretically and five transferrin fractions diagnostic at the species level are identified. A model of the evolution of Cynomys from an ancestral Spermophilus population is proposed that integrates available cytological, serological, morphological, paleontological, and zoogeographical data.Keywords
