Open AccessAccuracy of prediction of simulated polygenic phenotypes and their underlying quantitative trait loci genotypes using real or imputed whole-genome markers in cattle
More accurate genomic predictions are expected when the effects of QTL (quantitative trait loci) are predicted from markers in close physical proximity to the QTL. The objective of this study was to quantify t...

Open AccessRecombination locations and rates in beef cattle assessed from parent-offspring pairs
Recombination events tend to occur in hotspots and vary in number among individuals. The presence of recombination influences the accuracy of haplotype phasing and the imputation of missing genotypes. Genes th...

Open AccessComparison of molecular breeding values based on within- and across-breed training in beef cattle
Although the efficacy of genomic predictors based on within-breed training looks promising, it is necessary to develop and evaluate across-breed predictors for the technology to be fully applied in the beef in...

Open AccessAccuracy of direct genomic breeding values for nationally evaluated traits in US Limousin and Simmental beef cattle
In national evaluations, direct genomic breeding values can be considered as correlated traits to those for which phenotypes are available for traditional estimation of breeding values. For this purpose, estim...

Open AccessAccuracies of genomic breeding values in American Angus beef cattle using K-means clustering for cross-validation
Genomic selection is a recently developed technology that is beginning to revolutionize animal breeding. The objective of this study was to estimate marker effects to derive prediction equations for direct gen...
