The blockwise SFS (bSFS). a The bSFS is computed by partitioning sequences into short blocks, identifying mutation configurations, and noting their respective counts. b Example bSFS configurations for a sample from a single population. Genealogical relationships for a sample of size 5 can be generated by three types of topologies (top, middle, and bottom rows). Ignoring information on the phase, the branches can be classified by the number of tips they are ancestral to, i.e., singletons (red), doubletons (blue), tripletons (orange), and quadrupletons (black). Further, mutations on these branches give rise to different bSFS configurations, i.e., vectors \(\underline {k}\)
