Resolving sampling and population-size biases in domestication genomics supports a South Asian origin of walnuts
Our results clarify the long-standing debate on the geographic origin of walnut domestication and demonstrate that an optimized, model-aware use of STRUCTURE can substantially improve population-genetic inference in domestication studies and other systems characterized by complex demography.
