The effect of dominance and mating system on the site frequency spectrum (SFS). a The SFS from an outcrossing species simulated under different DFEs and h values. Note that different combinations of DFEs and values of h yield similar SFS. b The SFS for the same DFEs and values of h as in a for a highly selfing species. Differences in h result in large differences in the SFS in selfing species, allowing us to reliably co-estimate the DFE and h. c A schematic of the species history between A. thaliana and A. lyrata. d Examples of the relationship between h and s under the three different models of dominance tested here
