Correction to: Genomic evaluation for a three-way crossbreeding system considering breed-of-origin of alleles

Genetics Selection Evolution, 2017
After publication of our article [1], we found a typo in the formula to build the genomic relationship matrix using allele frequencies across all genotyped pigs (matrix) and the genomic relationship matrix using breed-specific allele frequencies (matrix),

Combining genomic and genealogical information in a reproducing kernel Hilbert spaces regression model for genome-enabled predictions in dairy cattle. [PDF]

PLoS ONE, 2014
Genome-enhanced genotypic evaluations are becoming popular in several livestock species. For this purpose, the combination of the pedigree-based relationship matrix with a genomic similarities matrix between individuals is a common approach. However, the

Investigating inbreeding in the turkey (Meleagris gallopavo) genome

Poultry Science, 2021
: The detrimental effects of increased homozygosity due to inbreeding have prompted the development of methods to reduce inbreeding. The detection of runs of homozygosity (ROH), or contiguous stretches of homozygous marker genotypes, can be used to ...

Comparison on genomic predictions using three GBLUP methods and two single-step blending methods in the Nordic Holstein population

Genetics Selection Evolution, 2012
Background A single-step blending approach allows genomic prediction using information of genotyped and non-genotyped animals simultaneously. However, the combined relationship matrix in a single-step method may need to be adjusted because marker-based ...

Genome-Wide Association Study of the Relationship Between Matrix Metalloproteinases and Intracranial Aneurysms

Journal of Clinical Neurology, 2022
Matrix metalloproteinases (MMPs) are expected to play an important role in extracellular matrix (ECM) remodeling in response to hemodynamic stress. We investigated the association between MMPs and intracranial aneurysms (IAs) via a genome-wide association study (GWAS) of IAs.A GWAS data set of 250 IAs and 294 controls was used to analyze the genetic ...

Comparison of analyses of the QTLMAS XIV common dataset. I: genomic selection [PDF]

, 2011
Background - For the XIV QTLMAS workshop, a dataset for traits with complex genetic architecture has been simulated and released for analyses by participants. One of the tasks was to estimate direct genomic values for individuals without phenotypes.

Pre-selecting markers based on fixation index scores improved the power of genomic evaluations in a combined Yorkshire pig population

Animal, 2020
Combining different swine populations in genomic prediction can be an important tool, leading to an increased accuracy of genomic prediction using single nucleotide polymorphism (SNP) chip data compared with within-population genomic.

A fast indirect method to compute functions of genomic relationships concerning genotyped and ungenotyped individuals, for diversity management

Genetics Selection Evolution, 2017
Background Pedigree-based management of genetic diversity in populations, e.g., using optimal contributions, involves computation of the $${\mathbf{Ax}}$$ Ax type yielding elements (relationships) or functions (usually averages) of relationship matrices.

How to achieve a higher selection plateau in forest tree breeding? Fostering heterozygote × homozygote relationships in optimal contribution selection in the case study of Populus nigra

Evolutionary Applications, 2021
In breeding, optimal contribution selection (OCS) is one of the most effective strategies to balance short‐ and long‐term genetic responses, by maximizing genetic gain and minimizing global coancestry.
