  1. The global accuracy of the second validation set = 99.34%. *Prediction accuracy based on functional copy (haploinsufficiency effect); N – number of samples; D – dura; T – tenera; P – pisifera. For (M1, M2), both T/T and A/A are sh Deli Dura/sh Deli Dura as wild type; M1 - T/C and C/C are sh Deli Dura/sh MPOB and sh MPOB/sh MPOB; M2 - T/A and T/T are sh Deli Dura/sh AVROS and sh AVROS/sh AVROS.
