Fig. 4From: Single nucleotide polymorphisms in native South American Atlantic coast populations of smooth shelled mussels: hybridization with invasive European Mytilus galloprovincialisStructure plots for the 19 studied populations (K = 5). Each individual is represented by a single vertical line broken into five coloured segments, with lengths proportional to each of the K inferred clusters. Abbreviation of the samples is provided in Table 1. Vertical black lines separate the populationsBack to article page
