^a According to the ISO 3166–1 alpha 3 codes (http://en.wikipedia.org/wiki/ISO_3166-1_alpha-3). ^b Sub-sample build with the aim to study a possible effect of differences in sample size among geographic regions, on STRUCTURE analysis.
Countries of origin were grouped into larger regional groups, for easiness of representation and statistical tests.
