Figure 3From: Phenotype/genotype sequence complementarity and prebiotic replicator coexistence in the metabolically coupled replicator systemCoexistence of metabolic and parasitic replicators in Model I. The rows of the figure differ in the number of diffusion steps per update: first row: D = 0, second row: D = 4; third row: D = 100. x- and y-axes are metabolic (h) and replication (r) neighbourhood sizes respectively (N: von Neumann neighbourhood; 3: 3×3, 5: 5×5, 7: 7×7, 25: 25×25 and 37: 37×37 Moore neighbourhoods). The gray-scale shades of the boxes correspond to average replicator densities (%, see scale bar) on the whole grid at the end of the simulations (at t = 1.000). The numbers within the boxes of the panels indicate the average ratio of the numbers of phenotype- and genotype forms of metabolic and parasite replicators at the end of the simulations (100 × Phenx/Genx, x = 1, .., 3 and Parasite means both replicator-forms) in five replicate runs of the simulation program in each parameter set. Zeros mean that the system collapses (no replicator survives to t = 1.000). Replication constants of metabolic replicators: k 1p = 3.0, k 1g = 3.0, k 2p = 5.0, k 2g = 5.0 , k 3p = 7.0, k 3g = 7.0. Replication constants of parasite replicators k 4p = 9.0 and k 4g = 9.0. Subscripts p and g denote phenotype-form and genotype-form of replicator types, respectively.Back to article page
