Mark connection functions. Mark connection function p _ij (s) for (a) genes and (b) operons. Analogously as in Figure 5, the full curves denote p₁₁(s), the dotted curves p₂₂(s) and the dashed curves p₁₂(s). The functions show that the maxima in Fig. 5 result only from different frequencies of inter-point distances, while the probabilities of being isolated or regulated depend monotonously on the interpoint distance s.
