The two alleles chosen do not affect the fitness of flies in the lab environment, so Kerr and Wright could be confident that if changes in the frequency of normal and forked phenotypes occurred, they would not be due to natural selection.
Using a larger breeding population would not be expected to alter the outcome of the experiment.
It might knock the old theory away completely because all of the new knowledge doesn't support the theory or it could change it because some of the new information supports the old stuff.
