  1. Assigned: parameters set in the program; Estimates (A): estimated by using a reaction norm model with pedigree information; Estimates (G): estimated by using a reaction norm model with genomic information
  2. * Cov(a0,a1)= ∑2 ∗ pi ∗ (1 − pi) ∗ mi ∗ ni, where pi is the frequency of one allele of the ith QTL, mi is the effect of the ith QTL for α0, and ni is the effect of the ith QTL for α1
