  • Genetic correlations (rG) were calculated as Embedded Image , where cov12 is the covariance of trait means of replicate individuals of a RI line, and VG1 and VG2 are the among-line variance components for those traits (see Table 4). A 95% confidence interval (in parentheses below each value of rG) was estimated using a z-transformation (Sokal and Rohlf 1995, p. 577). Correlations in italics have confidence intervals not encompassing zero. rG values greater than the theoretical maximum of 1.0 are statistical artifacts resulting from sampling variance, and confidence intervals for these estimates are undefined.
