—Historical demography of the Lake Whitefish species pairs. (A) Observed joint allele frequency spectrum (JAFS) for normal (-N; x axis) and dwarf (-D; y axis) populations for each of four lakes (T = Témiscouata, E = East, I = Indian, and C = Cliff), obtained by projection of empirical data to 13 diploid individuals per population. For each JAFS, the color scale indicates the number of SNPs falling in each bin defined by a unique combination of the number of derived allele observed in normal and dwarf populations. (B) Predicted JAFS of the fittest model for each lake. (C) Representation of the fittest model for each lake.
