Population structure based on genetic clustering in STRUCTURE (Pritchard et al. 2000) using all loci. a ΔK for each value of K (putative number of populations), averaged over ten replicates. The peak at K = 2 shows the most likely number of genetic clusters within the sample. b STRUCTURE barplot for K = 2. Columns are individuals, with the proportion of an individual’s genotype assigned to each cluster (K) denoted by dark blue or light blue
