Table 2.
Genetic differentiation between designated groups of specimens representing putative subspecies. Numbers above the diagonal are average pairwise sequence divergence (%) based on Cytb sequences. Numbers below the diagonal are FST values based on genome-wide SNP data. Mictomys borealis smithi is split into west and east considering separate supported mtDNA lineages from these regions. NA = not applicable based on a lack of sampling for genome-wide SNPs from these regions.
