GEenome typing of autochthonous cattle and sheep breeds in Croatia

The national program protection the endangered breed of domestic animals requests reliable evidence of originality of breeds. Beside good knowings of the phenotypic features, necessarily is knowings of genetic structure of breeds, their variability, similarity and distance in relation to cognate populations. The genetic characterization in Croatia include autochthonous breeds bovines and bovides. Genetic polymorphisms at the protein- (blood groups, blood and milk proteins) and DNA-level (microsatellites, mitochondrial DNA) can be successfully used for population analysis and for establishing relationships within and among species. On the basis of the research blood protein polymorphism and mtDNA markers have been estimated the genetic distances among three cattle breeds (Istrian cattle, Slavonian-syrmian podolian cattle and busha). Rare breeds of sheep (Ruda sheep, Pag island sheep and Krk island sheep) has been typed using several methodological approaches: blood protein polymorphisms, microsatellite markers and mitochondrial DNA.
