Tracking Zebu Introgression in Mediterranean Cattle Breeds
A recent work investigating genetic origin, admixture and population history of primitive European cattle highlighted, by using genome-wide single nucleotide polymorphisms, zebu gene flow in the Balkan and Italian Podolic cattle populations. Haemoglobin protein polymorphism analysis in Italian breeds highlighted the presence of zebuine markers in both Italian Podolic and Alpine Grey cattle. Based on the above evidences, we here specifically look for genomic regions of zebuine ancestry in a different dataset of 50K genotypes from Mediterranean breeds including 29 Marismena (Spain); 30 Bazadaise and 30 Gasconne (France); 24 Alpine Grey, 97 Piemontese, 51 Chianina, 5 Marchigiana, 121 Romagnola…
Genome-wide characterization of local cattle breeds from central and western Mediterranean
Following-up on previous studies that investigated genetic relationships among several world-wide cattle breeds using genome-wide SNP data, we focus here on the central and western part of the Mediterranean. Notably, 50K genotypes from 30 Marismeña (Spain); 24 Guelmoise (Algeria); 46 Brune de l’Atlas Fauve, 15 Brune de l’Atlas Grise, and 15 Blonde du Cap (Tunisia); 29 Modicana and 30 Cinisara (Sicily); 24 Podolica Italiana (Southern continental Italy); 34 Chianina and 24 Romagnola (Central Italy); 23 Modenese, 24 Reggiana, 23 Alpine Grey and 50 Pezzata Rossa Italiana (Northern Italy); 50 Bruna Italiana and 50 Frisona Italiana were considered. When included in a world-wide dataset, the three…
