Fig. 3From: The early events underlying genome evolution in a localized Sinorhizobium meliloti populationMismatch distribution analysis for concatenated genes carrying SNPs. Graphs of the mismatch distribution are shown for each replicon and for the two halves of the chromosome. The x-axis shows the observed distribution of pairwise nucleotide differences, with frequency plotted on the y-axis. The values of the moment estimator Tau (τ), and the Raggedness index r and R 2 statistics are shownBack to article page
