  1. Note: The D/A was calculated according to the formula (F1-MP)/(HP-MP) by expression abundance; “++”, extremely high parental expression (D/A greater than 2); “+”, high parental expression (D/A greater than 0.5 and below 2); “+−”, additive expression (D/A greater than − 0.5 and below 0.5); “-”, low parental expression (D/A greater than −2 and below − 0.5); “--”, extremely low parental expression (D/A below − 2)
