Figure 3.

Phenotypic space re-scaled by mutational (co)variance for each motif. Phenotypic values from 100–500 are represented as a grid that is deformed such that distances between phenotypes, d_μ, in this new depiction represent equal amounts of mutational variation. For visual reference, the locations of the nine populations from Figure 2 are plotted as black dots in this new mutational space. Note that this re-scaling may cause the 2-dimensional phenotypic space to curve outward into higher dimensions, but it is represented here as the projection of this curved manifold onto a plane.
