There were five generations of selection with four replicates, and a selected proportion of 20%.
With a selected proportion of 5%, for example, response to mass selection is reduced by only 7% when h = 0.10 but by 21% when h = 0.50 (Table 1).
With a selected proportion of 5%, the Bulmer effect always reduced response by 27% in GS schemes, irrespective of the accuracy.
There is a need for experiments that will include all CpG sites in the genome and that will shed light on the true epigenetic status of a cell instead of a selected proportion of the genome.
With a selected proportion of 25% (using the scale HAM-Nat-BPC) the net gain of successfully completed study episodes over the base rate is expected to rise from 70.1%to83.1%1%.
With the HAM-Nat-BPC and a selected proportion of ¼, an absolute gain of 13.0% in the proportion of successful applicants is expected and this corresponds to an effect size of h =.32 (computed by arcsin-transformation of proportions; h is equivalent to d) [ 38] (pp. 179).
Technically, this is related to the question of whether the logistic regression curve estimated from the upper quartile of our sample (corresponding to a selected proportion of 25%) extends to the lower quartile in the same way as the curve estimated with the full sample information does.
For example, for a phenotypic variance of σ P = 1, and a heritability of the unselected base-generation of h0 = 0.3, an initial accuracy of genomic EBV of r g g ˆ 0 = 0.8, and a selected proportion of 5%, so that k = 0.86, the initial variance of genomic EBV equals 0.8 × 0.3 × 1 = 0.192 and the equilibrium variance of genomic EBV equals 0.192/1.86 = 0.103.
We emphasised the analysis at α=15%, which is a common select proportion used by CIMMYT programmes.
The program extracted a randomly selected proportion of trees of the target species.
A randomly selected proportion of papers, double-coded to check for accuracy of paper inclusion, showed perfect agreement between the authors.
