An End to Endless Forms: Epistasis, Phenotype Distribution Bias, and Nonuniform Evolution

The effect of developmental plan density on phenotype distribution.

(A) The percentage of visible phenotypes out of the potential phenotypes as a function of the developmental plan density, c. The regulatory dimension, r, and the phenotypic dimension, k, are both set to 14. Each point represent the average of 1,000 different plans. For a given density value, c, each entry in the matrix is attributed with a nonzero value (either +1 or −1) with probability c. (B) The number of variable traits, ν (i.e., phenotypic elements that are active in at least one phenotype) as a function of the developmental plan density, c. The experimental settings are identical to those described in Figure 7A. (C) The percentage of visible phenotypes out of the 2 ν achievable phenotypes as a function of the developmental plan density, c.
