A researcher performs a lab experiment on flies where she monitors the frequency of an allele called "S." She works with 24 populations, each with an initial starting frequency for S of 0.1. For ten generations she transfers offspring of each generation to a new vial to produce the next generation. For twelve populations she randomly selects 16 flies to transfer each generation (treatment 1), while for the other 12 populations she transfers 4000 flies (treatment 2). After a total of 10 generations she finds the following allele frequencies for the 24 populations:

Treatment 1: 0.55, 0.01, 0.2, 0, 0.1, 0, 0.1, 0.5, 0.05, 0, 0.4, 0

Treatment 2: 0.85, 0.8, 0.9, 0.8, 0.75, 1, 0.8, 1, 0.9, 1, 0.85, 1

1. Is the S allele beneficial, deleterious, or neutral?

2. What is an evolutionary explanation for why the final frequencies differ so much between the treatments?
