Comparison of analyses of the QTLMAS XIV common dataset. I: genomic selection [PDF]

, 2011
Background - For the XIV QTLMAS workshop, a dataset for traits with complex genetic architecture has been simulated and released for analyses by participants. One of the tasks was to estimate direct genomic values for individuals without phenotypes.

Deregressing estimated breeding values and weighting information for genomic regression analyses [PDF]

Genetics Selection Evolution, 2009
Genomic prediction of breeding values involves a so-called training analysis that predicts the influence of small genomic regions by regression of observed information on marker genotypes for a given population of individuals. Available observations may take the form of individual phenotypes, repeated observations, records on close family members such ...

Estimation of genomic breeding values using the Horseshoe prior [PDF]

BMC Proceedings, 2014
A method for estimating genomic breeding values (GEBV) based on the Horseshoe prior was introduced and used on the analysis of the 16(th) QTLMAS workshop dataset, which resembles three milk production traits. The method was compared with five commonly used methods: Bayes A, Bayes B, Bayes C, Bayesian Lasso and GLUP.The main difference between the ...

Genomic prediction of breeding values using previously estimated SNP variances [PDF]

Genetics Selection Evolution, 2014
Genomic prediction requires estimation of variances of effects of single nucleotide polymorphisms (SNPs), which is computationally demanding, and uses these variances for prediction. We have developed models with separate estimation of SNP variances, which can be applied infrequently, and genomic prediction, which can be applied routinely.SNP variances

Estimation of the Accuracy of Genomic Breeding Value in Hanwoo (Korean Cattle) [PDF]

Journal of Animal Science and Technology, 2013
본 연구는 농협 한우개량사업소 후대검정우 552두의 도체중, 배최장근단면적, 등지방두께 및 근내지방도를 측정한 후 고밀도 SNP 패널(777K)을 사용하여 유전체 혈연 행렬(Genetic Relationship Matrix, GRM)을 추정하고 GBLUP (Genomic Best Linear Unbiased Prediction) 방법으로 GEBV (Genomic Estimated Breeding Value)를 구하여 교차 검증(Cross-validation) 방법으로 그 정확도를 추정함으로써 유전체 선발 기법을 한우 유전평가 체계에 적용하기 위한 기초자료로 이용하고자 수행하였다.
