Quantitative genetics model as the unifying model for defining genomic relationship and inbreeding coefficient. [PDF]

PLoS ONE, 2014
The traditional quantitative genetics model was used as the unifying approach to derive six existing and new definitions of genomic additive and dominance relationships.

Genome-wide assessment and mapping of inbreeding depression identifies candidate genes associated with semen traits in Holstein bulls

BMC Genomics, 2023
Background The reduction in phenotypic performance of a population due to mating between close relatives is called inbreeding depression. The genetic background of inbreeding depression for semen traits is poorly understood.

Assessment of genomic inbreeding in Polish Konik horses

Polish Journal of Veterinary Sciences, 2017
Abstract The aim of this study was to assess the inbreeding coefficient of Polish Konik horses based on runs of homozygosity (ROH). Ninety six horses kept in 6 herds located across Poland were genotyped with the use of EquineSNP60 BeadChip (Illumina).

Efficient genome ancestry inference in complex pedigrees with inbreeding [PDF]

Bioinformatics, 2010
Abstract Motivation: High-density SNP data of model animal resources provides opportunities for fine-resolution genetic variation studies. These genetic resources are generated through a variety of breeding schemes that involve multiple generations of matings derived from a set of founder animals.

Estimation of the Inbreeding Coefficient through Use of Genomic Data [PDF]

The American Journal of Human Genetics, 2003
Many linkage studies are performed in inbred populations, either small isolated populations or large populations with a long tradition of marriages between relatives. In such populations, there exist very complex genealogies with unknown loops. Therefore, the true inbreeding coefficient of an individual is often unknown.

Management of Genetic Diversity in the Era of Genomics

Frontiers in Genetics, 2020
Management of genetic diversity aims to (i) maintain heterozygosity, which ameliorates inbreeding depression and loss of genetic variation at loci that may become of importance in the future; and (ii) avoid genetic drift, which prevents deleterious ...

Fine-tuning genomic and pedigree inbreeding rates in equine population with a deep and reliable stud book: the case of the Pura Raza Española horse

Journal of Animal Science and Biotechnology, 2022
Background Estimating inbreeding, which is omnipresent and inevitable in livestock populations, is a primary goal for management and animal breeding especially for those interested in mitigating the negative consequences of inbreeding.

Grid search approach to discriminate between old and recent inbreeding using phenotypic, pedigree and genomic information

BMC Genomics, 2021
Background Although inbreeding caused by the mating of animals related through a recent common ancestor is expected to have more harmful effects on phenotypes than ancient inbreeding (old inbreeding), estimating these effects requires a clear definition ...

Temporal and region‐specific variations in genome‐wide inbreeding effects on female size and reproduction traits of rainbow trout

Evolutionary Applications, 2022
Recent studies have shown that current levels of inbreeding, estimated by runs of homozygosity (ROH), are moderate to high in farmed rainbow trout lines.
