Polymorphism and its Relationship to Chromosomal and Morphological Variation in Peromyscus
Leucopus and Peromyscus Gossypinus
W. Robbins, Michael H. Smith, Michael C. Wooten, and Robert K. Selander
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.
