A recent work investigating genetic origin, admixture and population history of primitive European cattle highlighted, by using genome-widesingle nucleotide polymorphisms, zebu gene flow in the Balkan and Italian Podolic cattle populations. Haemoglobin protein polymorphismanalysis in Italian breeds highlighted the presence of zebuine markers in both Italian Podolic and Alpine Grey cattle. Based on the aboveevidences, we here specifically look for genomic regions of zebuine ancestry in a different dataset of 50K genotypes from Mediterranean breedsincluding 29 Marismena (Spain); 30 Bazadaise and 30 Gasconne (France); 24 Alpine Grey, 97 Piemontese, 51 Chianina, 5 Marchigiana, 121Romagnola, 24 Podolica, 24 Modenese, 30 Reggiana, 30 Cinisara and 30 Modicana (Italy); 24 Guelmoise (Algeria); 24 Cika (Slovenia), 43Illyrian Mountain Buša (Albania). Additional taurine and zebuine breeds from previously published studies are also included in the analyses.Special emphasis in genetic analyses is also given to the identification of genomic regions potentially associated with a phenotypic trait observedin several taurine breeds as well as in some zebuine breeds, characterized by calves having a fawn coat at birth, while turning to various shadesof grey in adult animals. The obtained results contribute to a better characterization of history and genetic structure of Mediterranean cattlebreeds.
