Figure 1.

Summary of genetic variant frequency across simulated outbreaks. We simulated 10 outbreaks for each combination of 6 bottleneck sizes and 3 mutation rates (180 in total). A) Mean proportion of cases in the outbreak who shared at least 1 variant with another host. B) Distribution of shared-variant group size for different bottleneck sizes, with a mutation rate of 5 × 10⁻⁴ per genome per generation.
