WebSelective sweeps can be ‘hard’, where a single adaptive allele sweeps through the population, or ‘soft’, where mul-tiple adaptive alleles at the same locus sweep through the population at the same time [9]. By definition, whether a sweep is hard or soft in a given population sample is WebMar 7, 2024 · To date, mounting evidence indicates that hard selective sweeps might not be the dominant mode of adaptation in many species 33,34.
