Bar graph of the genetic admixture analysis of individual ducks. All duck species in one admixture analysis. Each bar represents one individual and colours indicate membership in a certain cluster as identified with STRUCTURE without using prior information. Individual IDs are explained in the text and additional file 4 and additional file 6. On the y-axis the percentage of membership in a certain cluster is given. For instance, individual ATHO001 (individual 1 from the Anas platyrhynchos locality in Austria) is almost 100% assigned to the light blue cluster, while individual CARM009 (from a Canadian locality) is mainly assigned to the light blue, but also with about 15% to the purple cluster (an effect of genetic admixture between these two otherwise discrete clusters). This file is scalable in order to retrieve details if needed.
