Clustering assignment of the ten Brazilian bovine breeds obtained by STRUCTURE analyses. Each of the 915 animals is represented by a thin vertical line that is divided into segments whose size and color correspond to the relative proportion of the animal genome corresponding to a particular cluster. Breeds are separated by thin black lines. Panels with K = 2 inferred clusters, taurine (red) and zebuine (green) breeds are discriminated; with K = 3, taurine Creole breeds of Iberian origin (blue) are further separated from the specialized taurine breeds (red) and zebuine (green); with K = 10 inferred clusters corresponding to the ten breeds, complex breed admixture patterns can be visualized.
