Table 2 Case-study results. Number of detected genes under positive selection after running GwideCodeML twice, one for each branch, using the three built-in nested models. *1. In site models, there is no dN/dS ratio variation among branches, therefore, it was run once | Model | Nested models (null vs. alternative hypotheses) | No. genes under positive selection in Sk branch | No. genes under positive selection in Sc branch |
|---|
| Branch | M0 vs. two-ratios | 83 | 31 |
| Branch-site | MAnull vs. MA | 137 | 96 |
| Site | M1a vs. M2a | 32*1 | 32*1 |
