The distribution of winner index values across cells in the population is affected by our experimental conditions. WI distributions are shown for the following experiments, where N is the total number of matched colony–Voronoi pairs used in analysis. (a) High initial cell density (ρhigh = 7.2 × 10−3 cell µm−2), exponential growth, N = 274, taken from one mapped agarose pad. (b) Low initial cell density (ρlow = 1.5 × 10−4 cell µm−2), exponential growth, N = 340, pooled from five mapped agarose pads. (c) Heat-shocked cells, low initial cell density (ρlow = 1.5 × 10−4 cell µm−2), N = 313, pooled from three agarose pads. Two measures of distribution width are quoted in the panels: the median absolute deviation (MAD) and lognormal coefficient of variation (cv).
