Figure 3From: Gene family evolution: an in-depth theoretical and simulation analysis of non-linear birth-death-innovation modelsProbability of family formation starting from a singleton, P(2)(1,n), versus the family size (n) for the quadratic BDIM (in double logarithmic scale). The model parameters are for D. melanogaster (blue), C. elegans (purple), H. Sapiens (red), Arabidopsis thaliana (green).Back to article page
