GC clusters by class and population. Box plots illustrate the distribution of each class of GC clusters within and between phylogenetic populations. Whiskers extend to the furthest value within 1.5 times the inter-quartile range from the 1st and 3rd quartiles. Outliers are plotted as empty circles. The number of strains analyzed for each population is provided in Table 1.
