Maximum likelihood estimation of individual ancestries calculated with the admixture software. We assumed a K-value 7 because it had the lowest cross-validation error. We took into consideration data from 39,257 SNPs used to genotype 12 caprine populations from Spain (Bermeya, Blanca de Rasquera, Malagueña, Murciano-Granadina, Florida, Mallorquina and Palmera), Tunisia, Burkina Faso (Sahel and Djallonké), Romania (Carpathian) and Switzerland (Saanen). This analysis shows that the Southern Spanish breeds, Malagueña and Murciano-Granadina, together with the Carpatian breed from Romania show evidence of potential introgression with North African (Tunisian) goats
