Accuracy of genomic breeding values in case of linkage equilibrium and unrelated training individuals
ثبت نشده
چکیده
The accuracy of genomic estimated breeding values (GEBVs) approaches the accuracy of pedigree-based BLUP (P-BLUP) EBVs with increasing number of SNPs fitted in the model even if SNPs and QTL are in linkage equilibrium [1]. For this to be true, it is not required that training individuals are related, but only that training and validation individuals are related. This is demonstrated below after basic definitions for linkage disequilibrium, cosegregation and additive-genetic relationships are given, and is finally completed by a simulation.

In the present study two genetically connected small and large populations were simulated and the effect of different sources of information from foreign populations on the accuracy of predicted genomic breeding values of young animals of the small population was investigated. A large population consist of 200000 animals over 15 generations and a small population consist of 5000 animals over 3 ...

This study aimed to investigate the effect of the method of estimating the effects of markers , QTLs distribution, number of QTLs, effective population size and trait heritability on the accuracy of genomic predictions. Two effective population sizes, 100 and 500 individuals, were simulated by QMSim software. A 100 cM genome including one chromosome was simulated where 500 SNPs and two diffe...
متن کاملAdding Genetically Distant Individuals to Training Populations Reduces Genomic Prediction Accuracy in Barley
one of the most important factors affecting genomic prediction accuracy appears to be training population (Tp) composition. The objective of this study was to evaluate the effect of genomic relationship on genomic prediction accuracy and determine if adding increasingly unrelated individuals to a Tp can reduce prediction accuracy. To accomplish this, a population of barley (Hordeum vulgare L.) ...
