Table 2 Tetraodon nigroviridis protein genes under positive Darwinian selection with significantly lower (^a) or higher (^b) distance to the human ortholog than other fish species. Duplicated genes are given with rate differences between the two copies according to the relative rate test of Tajima (1993) at the 5% level with one asterisk and at the 1% level with two asterisks.
