The aim of this work was to evaluate the utility of cluster cross-validation to determine the accuracy of genomic predictions of Braford (BO) and Hereford (HH) cattle genetic resistance to ticks.  aBeef cattle  aSingle nucleotide polymorphism  aTicks  aBovino  aCarrapato  aGado de Corte  aPolimorfismo de nucleotídeo único1 aOLIVEIRA, M.
