Invited review: Unknown-parent groups and metafounders in single-step genomic BLUP.

Journal of dairy science - 1 Feb 2022

Abstract excerpt

Single-step genomic BLUP (ssGBLUP) is a method for genomic prediction that integrates matrices of pedigree (A) and genomic (G) relationships into a single unified additive relationship matrix whose inverse is incorporated into a set of mixed model equations (MME) to compute genomic predictions. Pedigree information in dairy cattle is often incomplete. Missing pedigree potentially causes biases and inflation in...
