Three scenarios for scaling the global transposition probabilities. The burst factor λ(t) is given by Eq. (1). No burst (dotted): the transposition probabilities (θ, μ and ν) are constant for all cells, δ=0, γ=0. Burst, no regulation (dashed): there is a continuous burst in transposition activities, occurring at time t=T, that scales the basic probabilities by 100, γ=0. Burst, evolving regulation (solid): cells evolve regulation in transposition activities after the burst has occurred, the transposition probabilities asymptotically approach the global transposition probabilities over time, γ=0.001 (black solid) and 0.01 (grey). Other parameter values are as given in Table 1
