Figure 4From: Gene family evolution: an in-depth theoretical and simulation analysis of non-linear birth-death-innovation modelsProbability of family formation from a singleton, P(3)(1,n), versus the family size (n) for the cubic BDIM. The model parameters are for D. melanogaster (blue), C. elegans (purple), H. Sapiens (red), Arabidopsis thaliana (green).Back to article page
