Figure 2. Bayesian clustering analysis of all individuals with the program structure. Individual assignment to the most probable number of clusters K (3) as inferred from the ΔK statistic (ΔK for k2 = 84.6, ΔK for k3 = 713.1 and ΔK for k4 = 12.25). Arrow indicates a putative H. annuus x H. debilis hybrid, which was removed from later analyses.
