WebMay 11, 2024 · Selective sweeps can arise from multiple processes, including the de novo emergence of a selectively advantageous allele, selection on standing population haplotypic variation, and recurrent mutation to a selectively advantageous allele (Hermisson and Pennings 2005; Pennings and Hermisson 2006a, 2006b). The former scenario is a hard … WebAug 28, 2015 · In a hard selective sweep, the favoured allele appears through de novo mutation, while in a soft sweep, it is already segregating at low frequency in the population (standing genetic variation) or it arises from recurrent mutations (Hermisson & Pennings 2005; Pennings & Hermisson 2006a, b; Pritchard et al. 2010).
