Hierarchical Clustering of Samples based on Identity by State (IBS). Hierarchical clustering of identity‐by‐state pairwise values for all samples. IBS was calculated from SNP matrix using SNPrelate and used to create a tree using the “complete” method. Samples are color‐coded by population as in Figure 1. Dashed horizontal line represents the chosen cutoff for clonality, and nodes below this value with samples from the same site were designated as nodes and are visualized with leaf color. All but one sample were randomly removed from each clonal grouping for downstream analysis
