Note.— Both traits y1 and y2 are continuous. Posterior mean squared errors of the estimates are given in parentheses. σ2qj,1, σ2qj,2, and σqj,12 are the jth (j=1,2) QTL (co)variances of the two traits; σ2a,1, σ2a,2, and σa,12 are the polygenic (co)variances of the two traits; and σ2e,1, σ2e,2, and σe,12 are the residual (co)variances of the two traits.

J-12 = joint mapping for traits y1 and y2; S-1 = separate mapping for trait y1; S-2 = separate mapping for trait y2.
