Fig. 6From: Falciparum malaria from coastal Tanzania and Zanzibar remains highly connected despite effective control efforts on the archipelagoCharacterizing the impact of natural selection on sequence variation. a Site-frequency spectra for putatively neutral (fourfold degenerate) and putatively-selected (zerofold degenerate) sites. b Inferred distribution of population-scaled selection coefficients (4Nes) for each population, shown in discrete bins. Dark bars, estimates from raw SFS; light bars, estimates from smoothed SFS. Note logarithmic scale for vertical axis in both panelsBack to article page
