Note: AIC values were estimated by polyDFE for models with and without the effects of beneficial mutations, respectively (bold numbers showed significance < 0.05). The same applies to β_full and β_γ as well. β_full and β_γ were the shape parameters for full DFE and γ DFE model, respectively. β_max corresponds to the maximum value of those estimated by polyDFE for each ranked gene bin. AIC, Akaike information criterion; DFE, distribution of fitness effects.
