Genetic diversity analysis of the Uruguayan Creole cattle breed using microsatellites and mtDNA markers (original) (raw)

2013, Genetics and Molecular Research

The Uruguayan Creole cattle population (N = 600) is located in a native habitat in south-east Uruguay. We analyzed its genetic diversity and compared it to other populations of American Creole cattle. A random sample of 64 animals was genotyped for a set of 17 microsatellite loci, and the D-loop hyper-variable region of mtDNA was sequenced for 28 calves of the same generation. We identified an average of 5.59 alleles per locus, with expected heterozygosities between 0.466 and 0.850 and an expected mean heterozygosity of 0.664. The polymorphic information content ranged from 0.360 to 0.820, and the global F IS index was 0.037. The D-loop analysis revealed three haplotypes (UY1, UY2 and UY3), belonging to the European ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 12 (2): 1119-1131 (2013) E.
