Frequencies were calculated for (A) coxA, (B) ftsZ, and (C) gatB. Column ‘bases’ gives the total number of sequenced bases.

^a SNP-frequency per kilobase;

^b SNP-frequency per kilobase minus calculated error base line (0.28/kb) of Taq polymerase;

^c two-tailed P values from χ² calculations with Yates Correction (2×2 contingency table) for ^a;

^d two-tailed P values from χ² calculations with Yates Correction (2×2 contingency table) for ^b.
