Evolution of the Tp1 locus: likelihood value (lnL) and parameter estimates for six evolution models implemented.

aSites models of evolution. Nomenclature as in Yang et al. (2000). Model with highest likelihood for each locus is shown in italics.bWeighted average of dN/dS across all sites.cParameters in parenthesis are inferred (probabilities add up to 1); all others are estimated from the data. Significance levels indicate probability that ω>1 for the site:*p≥0.95;**p≥0.99 (no asterisks signifies p
