The proportion of rats that preferred lever C (i.e., mean selection of lever C of the last 3 days>60%) after preference reversal did not differ significantly from that recorded in initially drug-naïve rats (8.3 versus 2.3%, z<1.96).
Three generations of recurrent selection, 10 additive genes, population size of 100 plants, initial gene frequency of 0.06 (population mean as plant survival in the unselected population VLR1 at 375 g diclofopmethyl ha−1), selection proportion 0.2, heritability 50% and three generations of recurrent selection.
Three generations of recurrent selection, 10 additive genes, population size of 100 plants, initial gene frequency of 0.06 (population mean as plant survival in the unselected population VLR1 at 375 g diclofop-methyl ha−1), selection proportion 0.2, heritability 50% and three generations of recurrent selection.
Three generations of recurrent selection, two additive genes, population size of 100 plants, initial gene frequency of 0.06 (population mean as plant survival in the unselected population VLR1 at 375 g diclofop-methyl ha−1), selection proportion 0.2, heritability 50% and three generations of recurrent selection.

S: Mean selection coefficient; a measure of selection strength.
The forecasted response to selection was 11.2% in the next cycle with 20% S0 selection proportion.
· One-stage selection, with a selection proportion of 0.02 in sires and 0.99 in dams.
Additionally, selection proportions were also calculated for each round.
For most people shopping means selection".
