Geneticist Geoff Morris of Kansas State University sampled the genomes of about 2,000 varieties of sorghum, looking for differences. The genetic material, as well as information about the village where each variety of the cereal grain crop was grown, came from gene banks. Using those different genetic signatures and the location data, Morris and his colleagues...
