Early application of genomic selection relied on SNP estimation with phenotypes or de-
regressed proofs (DRP). Chips of 50k SNP seemed sufficient for an accurate estimation of …

Single-step genomic evaluation became a standard procedure in livestock breeding, and
the main reason is the ability to combine all pedigree, phenotypes, and genotypes available …

Background Bias has been reported in genetic or genomic evaluations of several species.
Common biases are systematic differences between averages of estimated and true …

During the last decade, genomic selection has revolutionized dairy cattle breeding. For
example, Nordic dairy cows (Denmark, Finland, and Sweden) born in 2018 were> 90% sired …

Bias in dairy genetic evaluations, when it exists, has to be understood and properly
addressed. The origin of biases is not always clear. We analyzed 40 yr of records from the …

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 …

The objective was to compare methods of modeling missing pedigree in single-step
genomic BLUP (ssGBLUP). Options for modeling missing pedigree included ignoring the …

Genomic selection was deployed in Lacaune dairy breed in 2015. Lacaune population split
in 1972 into 2 breeding companies with associated flocks, and there have been very few …

Metafounders are a useful concept to characterize relationships within and across
populations, and to help genetic evaluations because they help modelling the means and …

This study explores how the metafounder (MF) concept enhances genetic evaluations in
dairy cattle populations using single-step genomic best linear unbiased prediction …
