Microsatellite analysis characterizes Burkina Faso as a genetic contact zone between Sahelian and Djallonke sheep.
A total of 123 sheep belonging to the Djallonke, Mossi, and Burkina-Sahel breeds, along with 41 Spanish Xalda sheep were genotyped for 27 microsatellites. The pair Djallonke-Mossi had the highest between breeds molecular coancestry. Admixture analysis informed on the parental role of the Burkina-Sahel and Djallonke breeds. The Mossi breed was a hybrid population nearer to the Djallonke breed. Only half of the Mossi individuals were correctly assigned to their breed. The Burkina-Sahel and Djallonke breeds can be considered ancestrally different genetic entities. Differentiation between the Djallonke and Mossi breeds may be due to introgression of Sahelian sheep.
