Fixation probabilities in graph-structured populations under weak selection
Fig 3
Small graphs with extreme effects for temperature initialization.
The graphs with the largest or smallest values of ρ′ (which characterizes the likelihood of selected mutations to become fixed), and ρ′/ρ∘ (which quantifies the balance of selection versus drift) are shown for sizes 7 to 10. The Star graph minimizes ρ′ but maximizes ρ′/ρ∘ for these sizes. The largest ρ′ values arise for graphs with multiple components joined by single edges, while the smallest ρ′/ρ∘ ratios occur for Detour graphs.
