Correcting for base-population differences and unknown parent groups in single-step genomic predictions of Norwegian Red cattle.

Abstract excerpt

Bias and inflation in genomic evaluation with the single-step methods have been reported in several studies. Incompatibility between the base-populations of the pedigree-based and the genomic relationship matrix (G) could be a reason for these biases. Inappropriate ways of accounting for missing parents could be another reason for biases in genetic evaluations with or without genomic information. To handle these...
