Principal Coordinate Analysis (PCoA) of the Bruvo distances between individuals from the sympatric localities, including polyploid hybrids. Sympatric localities Sotk and Kuchak are in a, and Lchap and Lchaschen in b. Diploid individuals from non-sympatric localities are represented by the convex hulls, one per species (a D. armeniaca, D. valentini and D. unisexualis; b D. armeniaca, D. unisexualis, D. valentini and D. raddei). Individuals from the sympatric localities are identified as triangles (triploid backcrosses), filled circles (sexual and parthenogenetic diploids) or squares (tetraploids), and in different colour tones whenever from different localities
