The numbers in parentheses represent the percentage of this category among all QTLs in that group. The signs that follow the mode of inheritance indicate whether it is an increasing (+) or decreasing (−) QTL relative to M82. A statistical comparison between the different metabolite groups was conducted in each mode of inheritance using a χ2 test (with 1 df) by classifying the QTL into those that belong to this mode of inheritance and those that do not belong for each group.
