R.  aGenotype by environment interaction for tick resistance of Hereford and Braford beef cattle using reaction norm model.h[electronic resource]  c2016  aArticle 3.  aThe cattle tick is a parasite that adversely affects livestock performance in tropical areas. Although countries such as Australia and Brazil have developed genetic evaluations for tick resistance, these evaluations have not considered genotype by environment (G*E) interactions. Genetic gains could be adversely affected, since breed-stock comparisons are environmentally dependent on the presence of G*E interactions, particularly if residual vari-ability is also heterogeneous across environments. The objective of this study was to infer upon the existence of G*E interactions for tick resistance of cattle based on various models with different assumptions of genetic and residual variability.  aBovino  aCarrapato  aGado de corte  aGado Hereford1 aTEMPELMAN, R.
