In 2005 Lolle et al published controversial findings showing that the Arabidopsis thaliana plant repairs invalid genetic information using the grandparent as a kind of repair template. We have previously shown how a genetic repair operator (GeneRepair) can be used to correct invalid individuals in an evolutionary strategy. It has been shown that superior results are produced when the individual’s grandparent is used as the repair template in comparison to using the individual’s parent. This paper investigates whether the results produced by GeneRepair templates are affected by parameters of population size and number of generations. The results indicate that the grandparent template outperforms the parent template regardless of population or generation size. These findings further supports the controversial theory of Lolle et al.
