Sequence conservation. (A) Pairwise genetic distances in conserved genes between the four draft genomes and IAF-45-CD. Only genes conserved in all five genomes were used. The median pairwise distance, 0.0041, is shown with a dashed red line. (B) SNP density sampled in 50 kb windows across the genome. The median SNP density, 0.009, is shown with a dashed red line.
