[Genetic divergence of certain indigenous and commercial breeds of Eurasian cattle (Bos taurus)].

The genetic distances between cattle breeds were calculated and relationships between these breeds were analyzed on the basis of polymorphism of genes encoding seven blood proteins (N = 22 breeds) and four milk proteins (N = 14 breeds). The study was performed using cluster and cladistic analysis, as well as multidimensional scaling. The conventional systems of classification of cattle breeds are reviewed in genetic terms, and the history of breeds and their evolution are discussed.
