The SFS signature of a selective sweep compared to the neutral SFS. In the polymorphic table, black cells denote derived alleles, whereas the white cells denote ancestral alleles. Each column in the polymorphic table represents a SNP. Monomorphic sites have been excluded. a Neutral SFS and its respective polymorphic table. b SFS after a selective sweep and its respective polymorphic table
