Note: Best variables were chosen among the shared ones between both gene orders or independently with in each gene order based on the Akaike information criterion (AIC) value.

^aAkaike information criterion (AIC) value of the different combinations of predictors.

^bAdjusted R² (adj. R²) of the different combinations of predictors.

^cFor comparative reasons, the AIC and adjusted R² of the best in dependent variable are also provided.
