Stacked bar plot displaying genotypes of samples from colonies ordered by region and haplotype frequency. Each bar represents all samples from an individual colony. Sampling regions include Alberta, northern British Columbia (British Columbia), southern British Columbia (BC), California (CA), and Idaho (ID). A blue region name indicates that the colonies are monogyne, while a red region name indicates that colonies are polygyne. Genotype is indicated by color: green = Sm/Sm, brown = Sm/Sp, and Yellow = Sp/Sp. Genotype (green, brown, yellow) is shown for each individual worker, while phenotype (red, blue) relates to the colony as a whole. Colonies with “undetermined” social structure were excluded from this analysis (N = 4; see Additional file 1: Fig. S3)
