Microsatellite variation and evolution in the Peromyscus maniculatus species group.

摘要: Variation at 12 pure-repeat dinucleotide microsatellites from Peromyscus maniculatus was analyzed for samples of all species in the P. group and leucopus. Except one locus (Pml08) that amplified a product only maniculatus, these yielded reliable estimates variation across species; per-locus polymorphism allele-size distribution were not significantly different among or between any sampled mainland populations. Significantly lower levels alleles two populations insular-endemic sejugis consistent with expectation substantial founder effect suggest lack recent gene flow Phenetic analyses genetic distances based on shared allele frequencies uniformly produced well-supported trees entirely concordant priori corroborated relationships within group; this result obtained distance computed differences sizes. The microsatellite data do support hypothesis should be considered conspecific but yield strongly supported sister-group association keeni.
