  1. R2 is the phenotypic variance explained by the interaction
  2. aQTL_i and QTL_j are the two QTL involved in interaction
  3. bInterval_i and interval_j are the flanking markers of QTL_i and QTL_j respectively
  4. cPosition_i and position_j is the distance between QTL_i/QTL_j and the first marker of the relevant chromosome
  5. dRange_i and range_j is the position support interval of QTL_i and QTL_j respectively
  6. eAA is the estimated additive by additive effect
