Expected excess overlap versus gap length (variable clone length). The model from the text is implemented such that the length for each walking step is drawn from a gamma distribution with mean 100 kb and standard deviation 14.4 kb. Each gray point represents the average of 10,000 simulations of this process; the simulations are consistent with the model. The damped oscillations decay towards an asymptote near 51 kb, just over half the average length of a clone.
