Table 2. Codon-based maximum likelihood and Bayesian analysis for positively selected sites in exon 4 and exons 1, 2, and 3 combined.

Statistics with significance level p < 0.05, posterior probability >0.9 and Bayes Factor >50 are boldfaced. Consensus column summarizes methods which found the codon positively selected with significance level p < 0.2. Analysis was made using the Datamonkey server www.datamonkey.org (Delport et al., 2010; Pond, Frost & Muse, 2005).
