Correlation coefficients among genetic (GEN), geographic (GEO), and linguistic (LING) distances.

In parentheses are presented p values of Mantel tests by 5,000 permutations. Three-way tests were carried out by controlling the distance that does not appear in the subscript. All tests were based on the full-loci dataset, which contains information of 10 loci of 26 populations, and its derivatives by excluding populations of a specific language. Highlighted are highly significant (0.01 level) p values; n.s. stands for not significant at the 0.1 level.
