Histogram of sequence identities in a numerical simulation of proteome dynamics. The histogram of sequences identities of all paralogous pairs N_a(p) (filled circles) and duplicated pairs N_d(p) (open circles) in an artificial proteome generated by our numerical model for α = 0.33 and r_dup/ = r_del/ = 0.25 as described in the text. Solid line has the slope -4, while the dashed one is given by 6 with γ = 4 and the best fit value of r_del/ = 0.237.
