Improving genomic prediction of growth and wood traits in Eucalyptus using phenotypes from non-genotyped trees by single-step GBLUP
(Elsevier, 2019-03-28)
Genomic Best Linear Unbiased Prediction (GBLUP) in tree breeding typically only uses information from genotyped trees. However, information from phenotyped but non-genotyped trees can also be highly valuable. The single-step ...
Assessing the value of phenotypic information from non-genotyped animals for QTL mapping of complex traits in real and simulated populations
(2016-06-21)
Background: QTL mapping through genome-wide association studies (GWAS) is challenging, especially in the case of low heritability complex traits and when few animals possess genotypic and phenotypic information. When most ...
Comparison of GWA statistical methods for traits under different genetic structures: A simulation study
(2020-11-01)
Several methods have been used to perform genome wide association (GWA) studies, aiming to map quantitative trait loci (QTL) and candidate variants. The single-step genomic best linear unbiased prediction (ssGBLUP) method ...
Single-step genomic evaluation improves accuracy of breeding value predictions for resistance to infectious pancreatic necrosis virus in rainbow trout
(2018-01-01)
The aim of this study was to compare the accuracy of breeding values (EBVs) predicted using the traditional pedigree based Best Linear Unbiased Prediction (PBLUP) and the single-step genomic Best Linear Unbiased Prediction ...
Metafounders May Reduce Bias in Composite Cattle Genomic Predictions
(2021-08-20)
Metafounders are pseudo-individuals that act as proxies for animals in base populations. When metafounders are used, individuals from different breeds can be related through pedigree, improving the compatibility between ...
Genomic Heritability and Genome-Wide Association Studies of Plasma Metabolites in Crossbred Beef Cattle
(Frontiers Media Sa, 2020-09-24)
Metabolites, substrates or products of metabolic processes, are involved in many biological functions, such as energy metabolism, signaling, stimulatory and inhibitory effects on enzymes and immunological defense. Metabolomic ...
Weighted single-step genome-wide association study and pathway analyses for feed efficiency traits in Nellore cattle
(2020-01-01)
The aim was to conduct a weighted single-step genome-wide association study to detect genomic regions and putative candidate genes related to residual feed intake, dry matter intake, feed efficiency (FE), feed conversion ...
Development of genomic predictions for Angus cattle in Brazil incorporating genotypes from related American sires
(2022-02-01)
Genomic prediction has become the new standard for genetic improvement programs, and currently, there is a desire to implement this technology for the evaluation of Angus cattle in Brazil. Thus, the main objective of this ...
Identification of genomic regions related to age at first calving and first calving interval in water buffalo using single-step GBLUP
(Wiley-Blackwell, 2020-10-05)
In Brazil, water buffaloes have been used to produce milk for mozzarella cheese production. Consequently, the main selection criterion applied for the buffalo genetic improvement is the estimated mozzarella yield as a ...
