A researcher performs an experiment on fruit flies to monitor the change in allele frequency of an allele called
A. She starts with 24 populations, each with an initial starting frequency for A of 0.5. Flies are maintained for ten generations by transferring the offspring from each generation to a new vial, where they produce the next generation. For half of the populations she randomly selects 20 flies to transfer, while for the other half she randomly selects 200 flies to transfer. After ten generations she collects the following allele frequency data:

Treatment 1: 0.55, 0.6, 0.2, 0.9, 0.45, 0.35, 0.1, 0.65, 0.65. 0.55, 0.75, 0.35
Treatment 2: 0.85, 0.8, 0.75, 0.8, 0.75, 1.0, 0.8, 0.85, 0.9, 0.8, 0.85, 0.8

What is a plausible explanation for the differences between the treatments? Please make sure to explain your logic.
