Table 2 Observed numbers of convergent and parallel sites and expected numbers of convergent and parallel sites under neutral evolution. JTT-f_site model of amino acid substitution is used and all numbers are calculated using dataset 1. For low-elevation species, only sister-group species of the high-elevation species (Fig. 1) are presented here
