Table 1. Counts of genetically unique samples, relative to geographic regions. Unique samples and countries and regions are listed in Supplementary File S1, worksheet “uniques.” Detailed counts (per country) are given in Supplementary File S1, worksheet “clade summary.” Columns labeled 1-4 indicate clades, as identified in Figure 1, and listed in File S1, worksheet “uniques.” Summary counts by continent are given at the bottom, corresponding with F_ST results in Figure 5F.
