Biochemical Polymorphism and its Relationship to Chromosomal and Morphological Variation in Peromyscus Leucopus and Peromyscus Gossypinus

Lynn W. Robbins, Michael H. Smith, Michael C. Wooten, and Robert K. Selander

 

Abstract

Allozymic variation was used to examine patterns of geographic differentiation and variability in Peromyscus leucopus and P. gossypinus.  The pattern of relationships based on genetic similarity was not concordant with either recognized subspecific status of either species or with the major chromosomal subdivision in P. Leucopus.  The pattern was consistent with the isolation-by-distance model as tested by Mantel analysis, and differentiation at the variable loci was generally spatially autocorrelated.  Differences between the species were indicative of complete speciation with little or no hybridization in areas of sympatry.
