Single-step genomic BLUP with genetic groups and automatic adjustment for allele coding.

Genetics, selection, evolution : GSE - 2 Jun 2022

Strandén Ismo, Aamand Gert P, Mäntysaari Esa A

Abstract excerpt

BACKGROUND: Genomic estimated breeding values (GEBV) by single-step genomic BLUP (ssGBLUP) are affected by the centering of marker information used. The use of a fixed effect called J factor will lead to GEBV that are unaffected by the centering used. We extended the use of a single J factor to a group of J factors. RESULTS: J factor(s) are usually included in mixed model equations (MME) as regression effects but...
