Figure 4. Assignment of the 20 individuals in the RAPD dataset to genetic groups using STRUCTURE analyses for K = 3 optimal number of clusters (L(K) = -914.64). Each individual is represented by a column, which is partitioned in K coloured segments that represent the genetically based membership to each species cluster. The labels below indicate the species and specimens labels used in the RAPD (and partly sequencing) analysis.
