Adaptation – not by sweeps alone
... Finally, the sweep and polygenic models are not mutually exclusive. It may be that often the alleles with largest effect sizes (and without strongly negative pleiotropic effects) sweep to fixation, whereas much of the adaptive response is caused by smaller allele frequency shifts at many loci9. To u ...
