Fig. 7.

Bifurcation analysis for the SCQSS approximation of the stochastic auto-activation gene regulatory circuit Eqs. (54) and (55). This figure shows the bifurcation diagram for different values of the parameters of p₂. In these, solid lines correspond to $p_2^2$ = 1, dashed lines to $p_2^2$ = 0.9, dotted to $p_2^2$ = 0.8, and dashed-dotted lines to $p_2^2$ = 0.7 (recall that p₂ = p). Parameter values as given in Table VI.
