Residual and genetic variance estimates are presented for purebred traits 1, 2, and 3 and crossbred traits 23 and 123.

1Variances are on the diagonal, correlations are on the off-diagonal. Standard errors of the variances ranged from 0.035 to 0.074, and from 0.040 to 0.130 for the genetic correlations. Standard errors for each estimate are presented in Supplementary Table 2.

2Genetic variances after scaling are presented.
