Potential relationships between a crop and wild progenitor populations. Crops carry a subset of the neutral genetic variation found in their wild relatives. (A) Single origin of domestication. (B) Multiple domestication origins. Each numbered clade corresponds to a genetically and geographically definable group of wild populations; asterisks indicate clades sharing neutral variation with the crop.

Models of domestication bottlenecks. (A) The classic model (6). (B) The protracted model (5). Population sizes remain small for tens of hundreds of generations after the initial bottleneck, creating protracted and severe bottleneck effects. Values of k are shown for parameters used by Allaby et al. (5) in their simulations. (C) The protracted model shown with two independent domestication events, followed by admixture. NA, population size of the wild ancestor population; Nb, population size during the domestication bottleneck; d, duration (in generations) of the domestication bottleneck; k, bottleneck severity, calculated as Nb/d (9); Np, present-day crop population size.
