  • a Average ratio within the proviral clones of nonsynonymous change to synonymous change, calculated using PAML codeml.

  • b Average percent divergence of each animal's cloned quasispecies away from the inoculum. *, Mann-Whitney P value of <0.05; **, P value of <0.001.

  • c Average number of PNGs per env region from V1 to gp41. Note that N88 is not included in this region and therefore not represented in the average but is likely well conserved.

  • d T98098 sequence reads did not cover the N130 and N136 motifs, which were well conserved in the other macaques. Therefore, the average is likely a low estimate.
