Genetic Variation in the Silky Pocket Mouse (Perognathus flavus) in Texas and New Mexico
Lee TE and Engstrom MD. 1991. Genetic Variation in the Silky Pocket Mouse (Perognathus flavus) in Texas and New Mexico. Journal of Mammalogy. 72(2):273-285
We examined allozymic exchange across a contact zone between Perognathus flavus and P. merriami in Texas and New Mexico by use of starch-gel electrophoresis. Frequency differences between the taxa were pronounced; the overall Rogers' genetic similarity was 0.82. P. flavus and P. merriami were sympatric at six localities and, based on the electrophoretic data, introgression between them appeared limited. These results contrast with those of others who concluded that the two taxa intergraded in this zone of overlap, based on morphological analysis. In western Texas and eastern New Mexico, P. flavus and P. merriami appear to interact as distinct biological species.
