Table 1. Variation of Wolbachia and mitochondrial genomes within host species.

We consider only individuals with cytoplasmic wRi-like infections. We compare the wRi-like infections to wMel from D. melanogaster. See also Table S1.

Wolbachia	N	L	π (Wolbachia)	L	π (mtDNA)
wRi	84	506,307	1.42×10−6	11,184	1.12×10−4
wSuz	9	506,307	2.07×10−5	11,178	5.31×10−3
wAnaa	8	506,307	3.48×10−5	11,184	4.06×10−3
wAnab	8	1,194,063	3.65×10−5	14,904	3.02×10−3
wMelc	91	1,209,286	1.06×10−5	14,492	5.34×10−4

N is the number of strains, L is the number of nucleotides analyzed, π is the average number of pairwise nucleotide differences per site.

^aData from [28] analyzed for only the 525 reference Wolbachia loci used in Figures 1 and 2 and only the mtDNA protein-coding data used in Figure 2.
