Maize domestication and expansion. a Sampling locations. b Estimates of effective population size over time (mutation rate =310−8, generation time = 1 year). Dashed lines represent bootstrapping results. The x axis is l o g10 scaled when time is less than 10,000 generations BP and linear when greater than 10,000 generations BP as indicated by the gray background. c The percentage of polymorphic sites versus distance from the maize domestication center. Abbreviations for populations: GuaHigh Guatemalan highlands, MexHigh Mexican highlands, MexLow Mexican lowlands, SA_Low South American lowlands, SW_US southwestern US highlands
