Model fits to joint allele frequency spectra (AFS) using nonsynonymous data. (A) Joint AFS for the human nonsynonymous data, the best fit model with DFE correlation w = 0.995, and the residuals between model and data. (B) Joint AFS for the Drosophila melanogaster nonsynonymous data and the best fit model with DFE correlation w = 0.967. (C) Joint AFS for the wild tomato nonsynonymous data and the best fit model with DFE correlation w = 0.905. In all three cases, residuals are small for almost all entries in the AFS, so to increase contrast the color range has been restricted to ±3. See supplementary figure S8, Supplementary Material online for plots showing the full residual range.
