Figure 5.

The 16 shapes of fitness landscapes of genotope (b). In the graph, each vertex represents one of the 16 possible geometric shapes of a fitness landscape on the truncated three-locus system that corresponds to genotope (b) in Figure 1. The shapes are determined by a collection of different tests for gene interactions. Two shapes are connected by an edge if they differ only by the sign of a single test. The labelling of the vertices follows [1, Table 5.1].
