For the intensity of selection (defined as the reciprocal of the proportion of individuals selected from a population to be used as parents) to be the same across different values of n, we used the following selection schemes.
Moreover, the accuracy increased with the intensity of selection.
The parameter β measures the intensity of selection.
The direct selection hypothesis predicts that only the environmental robustness of a trait should be correlated with the intensity of selection acting on that trait, while the congruence hypothesis predicts that both ER and GR should be correlated with the intensity of selection.
We used three measures of gene importance as proxies for the intensity of selection; whether a gene was lethal when knocked out, the Ka/Ks ratio and whether colony growth was affected by heterozygous gene knock-outs.
The expected strengths of the associations between these variables and fitness should depend on factors such as the intensity of selection for heterozygosity, the level of linkage disequilibrium in the population and the action of genetic drift [17], [18].
The parameter w controls the intensity of selection.
Altering the intensity of selection is one possible manipulation.
The parameter β measures the intensity of selection, similar to w above.
