The distribution of Bar genes in the ten generations and their percentage in the
offspring of heterallelic parents in generations 4 to 10 are shown in table 10.2. It
may be seen that after ten generations, 95 of the 108 lines had become
homallelic ...

Truncation Selection of Quantitative Variability We here consider truncation
selection of the additive effects of multiple strongly heterallelic loci on the same
character instead of the separate selection of weakly heterallelic loci as above.

In the heterotic case, on the other hand, the load (relative to the maximum
genotypes) tends to be large and the deviation from the heterallelic selective
peak (which is the same for both mean selective values and fitness if selection
values are ...
