Column two specifies the total number of QTL detected for each trait. Columns 3, 4 and 5 give the QTL with their respective additive, dominance and imprinting effects., R2a, R2d, R2i and Total R2 denote to the phenotypic variance explained by the, additive effect, dominance effect, imprinting effect and main QTL effect, respectively.
