Bovine breeds starded to be selected in the old world, during the 19thcentry. The starting populations werw varieties of cattle adapted by natural selection to the local enviroment. Now a days, a large quantityof spceialized bovine breeds are spread all over the world. Several ofthese are exploited for meat proction in Brazil. The objective of the present work was to investigate the genetic ralationsphip among some of these breeds, representing beef cattle from different categories: Caracu, a European breed adaptded to tropical environment, Simmental, a continental european breed, Aberdeen Angus, a representative of British Isles breeds, Canchim, a crossbred (5/8 Charolais, 3/8 Bos indicus) and Nellore, The most relevant Bos indicus beef cattle breed in Brazil.
