Genomic inbreeding coefficients using imputed genotypes: assessing differences among SNP panels in Holstein-Friesian dairy cows [PDF]

Frontiers in Veterinary Science, 2023
The objective of this study was to evaluate the effect of imputation of single nucleotide polymorphisms (SNP) on the estimation of genomic inbreeding coefficients. Imputed genotypes of 68,127 Italian Holstein dairy cows were analyzed. Cows were initially

Comparing pedigree and genomic inbreeding coefficients, and inbreeding depression of reproductive traits in Japanese Black cattle [PDF]

BMC Genomics, 2023
Background Pedigree-based inbreeding coefficients have been generally included in statistical models for genetic evaluation of Japanese Black cattle. The use of genomic data is expected to provide precise assessment of inbreeding level and depression ...

No Pedigree, No Problem: Genomic Inbreeding Tracks Genetic Rescue With High Resolution [PDF]

Evolutionary Applications
With increasing habitat fragmentation and population isolation, inbreeding becomes a pressing concern for the persistence of wildlife populations. Detailed inbreeding monitoring is crucial for assessing extinction risk and evaluating the effectiveness of

Using Pedigree and Genomic Data toward Better Management of Inbreeding in Italian Dairy Sheep and Goat Breeds

Animals, 2022
The inbreeding coefficient is an important parameter for livestock management. Small ruminant breeders and associations mainly rely on pedigree information, but genomic tools are gaining relevance, overcoming possible pedigree inconsistencies. This study

Genomic Inbreeding and Relatedness in Wild Panda Populations. [PDF]

PLoS ONE, 2016
Inbreeding and relatedness in wild panda populations are important parameters for panda conservation. Habitat loss and fragmentation are expected to increase inbreeding but the actual inbreeding levels in natural panda habitats were unknown.

Fine-scale assessment of ROH patterns and genomic inbreeding in diverse horse breeds using two SNP array densities [PDF]

BMC Veterinary Research
Background Inbreeding is caused by mating between related individuals and is associated with reduced fitness and performance. Generally, in the horse population, inbreeding is caused by geographically restricted areas and intensive natural or artificial ...

Genomic analysis of the inbreeding load for body weight, carcass and reproductive traits in the Rubia Gallega beef cattle population [PDF]

Genetics Selection Evolution
Background Inbreeding, resulting from mating between relatives, leads to inbreeding depression, which can be traced back to hidden ancestral inbreeding loads.

Exploring inbreeding depression in Brazilian Angus cattle population using pedigree and genomic data

Frontiers in Genetics
IntroductionInbreeding depression refers to the decline in performance caused by increased levels of inbreeding, which results from mating individuals with common ancestors.

Trends in genetic diversity and the effect of inbreeding in American Angus cattle under genomic selection

Genetics Selection Evolution, 2021
Background While the adoption of genomic evaluations in livestock has increased genetic gain rates, its effects on genetic diversity and accumulation of inbreeding have raised concerns in cattle populations.

The value of genomic relationship matrices to estimate levels of inbreeding

Genetics Selection Evolution, 2021
Background Genomic relationship matrices are used to obtain genomic inbreeding coefficients. However, there are several methodologies to compute these matrices and there is still an unresolved debate on which one provides the best estimate of inbreeding.
