The model predicts similar adjustment in parameters consistent to the phylogenetic relationship of species.
Experimental quantification of the Dl gradient (solid line) and model simulations (dotted lines). Shadowed area indicates mean±SD A–D) D. melanogaster (A, adjusted parameters shown in Table 1); and species gradient simulations according to Table 2 (B, busckii; C, simulans; D, sechellia). Experimental data was obtained from . V indicates ventral midline, y axis indicate normalized Dl levels, x axis indicate nuclei. See Table S5 for fit calculations.
