Methods to approximate reliabilities in single-step genomic evaluation.
Reliability of predictions from single-step genomic BLUP (ssGBLUP) can be calculated by matrix inversion, but that is not feasible for large data sets. Two methods of approximating reliability were developed based on the decomposition of a function of reliability into contributions from records, pedigrees, and genotypes. Those contributions can be expressed in record or daughter equivalents. Th...
متن کاملSingle-step methods for genomic evaluation in pigs.
Genetic evaluation based on information from phenotypes, pedigree and markers can be implemented using a recently developed single-step method. In this paper we compare accuracies of predicted breeding values for daily gain and feed conversion ratio (FCR) in Danish Duroc pigs obtained from different versions of single-step methods, the traditional pedigree-based method and the genomic BLUP (GBL...
متن کاملGenetic evaluation using single-step genomic BLUP in American Angus
Introduction Genomic selection in beef cattle has currently been performed with multistep methods, which uses deregressed EBV to estimate SNP effects and then direct genomic value (DGV) for selection candidates based on their genotypes (Meuwissen et al., 2001; Garrick et al., 2009). The main advantage of this approach is that the traditional BLUP evaluation is kept unchanged and genomic selecti...
متن کاملRunning head : Single - step genomic BLUP for Angus Genetic evaluation using single - step genomic BLUP in American Angus
Predictive ability of genomic EBV when using single-step genomic BLUP 1 (ssGBLUP) in Angus cattle was investigated. Over 6 million records were available on birth 2 weight (BW) and weaning weight (WW), almost 3.4 million on post-weaning gain (PWG), and 3 over 1.3 million on calving ease (CE). Genomic information was available on at most 51,883 4 animals, which included high and low EBV accuracy...
متن کاملComparison of two methods to approximate reliabilities of breeding values from test day model
INTRODUCTION Reliability or its square root, accuracy, is often reported by breeding organizations and required by Interbull along with estimated breeding values. In theory, reliability is calculated as a function of genetic variance and elements of the inverse of the coefficient matrix of the mixed model equations that are used to estimate breeding values. In practice, approximation methods ar...
