Figure 3.

Bayesian estimate of the ratio of omega values (ωP = Physalis dN/dS; ωS = Solanum dN dS) for each codon position. The gray region is the 95% highest posterior density (HPD) and the solid line is the mean of the ratios. If the HPD crosses the value 1 (dashed line) then the ratios are not significantly different. HPD's above the line indicate a higher ω for Physalis than Solanum S-alleles.
