dN/dS ratios were calculated from gene alignments using metagenomic sequences from a Synechococcus clade I population (A), metagenomic sequences from a Synechococcus clade IV population (B), simulated CC9311 sequences (C) and simulated CC9902 sequences (D). The dashed line indicates where dN/dS = 1 and selection is neutral.
