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.

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.

Inbreeding depression of reproductive traits in Japanese Black cattle using genomic information [PDF]

Animal Bioscience
Objective The objective of this study was to evaluate genomic inbreeding in Japanese Black cattle and its effects on reproductive traits. Methods The study analyzed reproductive records and single nucleotide polymorphism (SNP) data from Japanese Black ...

Genomic selection requires genomic control of inbreeding

Genetics Selection Evolution, 2012
Background In the past, pedigree relationships were used to control and monitor inbreeding because genomic relationships among selection candidates were not available until recently.

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.

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 ...

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 ...

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.

Commonly used genomic estimators of individual inbreeding in livestock

Czech Journal of Animal Science
: Management of inbreeding is one of the crucial parts of breeding programs in livestock populations. Traditionally, the inbreeding coefficient is calculated using pedigree data; however, it can also be estimated from genomic data.
