  1. G(A): model with a G matrix built with autosomal markers only; G(A) + G(X): model with an autosome G matrix and an X chromosome G matrix; Gc(A + X) + Pol: model with a G matrix built with all markers plus a residual polygenic effect; a,b,cCorrelations within a trait without common superscript differed significantly (P < 0.05), according to Hotelling-Williams’ t-test.
