Correlation coefficients between proportion variant at SNP sites in SIV from different hosts.

1Only sites synonymous in all reading frames and showing one or more differences from the inoculum in at least one host (N = 451 sites) were included. 2Only sites nonsynonymous in all reading frames and showing one or more differences from the inoculum in at least one host (N = 420 sites) were included. *Significance of correlation coefficient: P<0.05 (Bonferroni-correction for multiple testing). **Significance of correlation coefficient: P<0.01 (Bonferroni-correction for multiple testing). ***Significance of correlation coefficient: P<0.001 (Bonferroni-correction for multiple testing). †The correlation for nonsynonymous sites was significantly different (P<0.001 in each case; Bonferroni-correction for multiple testing) from the corresponding correlation for synonymous sites.
