Figure 2From: Phenotype/genotype sequence complementarity and prebiotic replicator coexistence in the metabolically coupled replicator systemCoexistence of metabolic 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 the sizes of metabolic (h) and replication (r) neighbourhood, 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 at the end of the simulations (100 × Phen x /Gen x , x = 1, .., 4) in five replicate runs of the simulation in each parameter set. Zero means the collapse of the system (no replicator survives to t = 1.000). Replication constants: k 1p = 3.0, k 1g = 3.0, k 2p = 5.0, k 2g = 5.0 , k 3p = 7.0, k 3g = 7.0, 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
