For the elements in the matrix, the estimate for the outbred control population is given on the top line and the estimate for the average value over all inbred lines is given on the bottom line. The phenotypic variance-covariance matrix (P) is the sum of the elements in this matrix (E) with those in Table 1 (G). Scale as in Table 1.

  • a Values in parentheses give the standard error of the estimate.

  • b Average estimates from the 52 inbred lines. Values in brackets give the standard deviation of the (co) variance across lines, not the standard error of the estimate.
