Hierarchical Structure analysis: A delta K method estimating that the uppermost hierarchical structure is composed of two main genetic clusters B corresponding barplot showing each individual as a vertical bar where each color corresponds to the admixture coefficient of the inferred genetic clusters; additional analyses within each of these two genetic clusters C-F showed that the first genetic cluster is composed of three genetic clusters (C, D) and the second one of two genetic clusters (E, F) totalizing an overall number of five genetic clusters across the whole dataset G genetic distance tree between genetic clusters based on the allele frequencies divergence among clusters H.
