Abstract Modelling population connectivity is central to biodiversity conservation and often relies on resistance surfaces reflecting multi‐generational gene flow. ResistanceGA (RGA) a common optimization framework for parameterizing these by maximizing the fit between genetic distances cost using maximum likelihood effect models. As reliability of this has rarely been studied, we investigated conditions its accuracy both prediction interpretation landscape features' permeability. We ran demo‐genetic simulations in contrasted landscapes species with distinct dispersal capacities specialization levels, corresponding reference scenarios. then optimized from simulated RGA. First, evaluated whether RGA identified drivers patterns, that is, distinguished Isolation‐by‐Resistance (IBR) patterns either Isolation‐by‐Distance or unrelated ecological distances. assessed predictive performance cross‐validation method, ability recover scenarios shaping structure simulations. IBR were well detected predicted great accuracy. This depended strength structuring, sampling design structure. Matching scale pattern focusing pairs connected through flow limiting overfitting further enhanced inference reliability. Yet, values departed values, making their extrapolation potentially dubious. While demonstrating value modelling, call caution provide additional guidance optimal use.
