snmf clustering on the N109 dataset: the probabilities of attribution to the most probable K = 4 clusters or ancestral populations are displayed in a bar plot for each individual. The morph of A. viridis sea anemones is coded by the shape above the diagram (triangle: var. rustica, circle: var. smaragdina, and square: var. rufescens). The individuals kept in the N85 dataset are identified by black stars below the diagram. The sampling sites are detailed in brackets (Vul: Vulcano, Ban: Banyuls, Tha: Thau, Sha: Southampton, and Ply: Plymouth). The four clusters are identified by the colours of the corresponding SVD clades
