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<95%). Significance levels for M3 is based on a Naïve Empirical Bayes (NEB) analysis, while that of models M2 and M8 is based in a Bayes Empirical Bayes (BEB) analysis (Yang, Wong, and Nielsen 2005).
