Fig. 2From: Intraspecific convergence of floral size correlates with pollinator size on different mountains: a case study of a bumblebee-pollinated Lamium (Lamiaceae) flowers in JapanPopulation genetic structure of L. album var. barbatum populations. a ΔK, an index used to determine the appropriate number of genetic clusters (K), peaked at K = 2. b Genetic structure of L. album var. barbatum inferred by using Bayesian clustering implemented in STRUCTURE with K = 2. Different genetic clusters are represented by different colorsBack to article page
