Figure 4.

The robustness of the selection process depends on the amount of cells that sense the signal. (A) Frequency of selection of the P-pattern (R_p in percentage) for 100 repetitions versus (B) the time τ spent at the intermediate parameter space vertex point of the path. The signal drives the change of the control parameters only in the number of cells detailed in the legend, located at the center of the tissue, according to (A) path 2a and (B) path 2b of Fig. 3, A and B, respectively. All parameter values as in Fig. 3. To see this figure in color, go online.
