Selective advantage of alleles during evolutions.

*not statistically significant. We determined allele frequencies during the populations’ histories. In order to determine the maximum fitness advantage attributable to the identified mutations we identified the generation at which the allele frequency was the greatest and determined fitness coefficients based on the rate of allele frequency increase to that point. Assuming the fitness benefit has been constant over the evolution experiment we inferred the size of the subpopulation at the commencement of the evolution experiment.
