a Principle component analysis of genetic variation based on 5,414 LD-filtered SNPs. The variance explained by PC1 and PC2 is 5.53% and 2.84%, respectively. b Maximum likelihood estimation of individual ancestries calculated with ADMIXTURE (Alexander et al. 2009) for all populations analysed, testing K values from 2 to 3 and based on 5,414 LD-filtered SNPs. Mean cross-validation error: K2 = 0.613; K3 = 0.617. SNZ South Island, New Zealand; TAH Tahiti; MOO Mo’orea; HUA Huahine; RAI Raiatea; MAU Maupiti.
