Pedigree and genomic-based inbreeding in Italian Holstein dairy cows

, 2020
Dairy cattle breeds have been exposed to intense directional selection for milk production traits over the last fifty years. Intense selection can cause loss of genetic variability and increased inbreeding.

Predicting rates of inbreeding: in populations undergoing selection [PDF]

, 2000
Tractable forms of predicting rates of inbreeding (Delta F) in selected populations with general indices, nonrandom mating, and overlapping generations were developed, with the principal results assuming a period of equilibrium in the selection process ...

Genomics‐informed management of ex situ populations

Conservation Biology, EarlyView.
Abstract The European Association of Zoos and Aquariums (EAZA) manages insurance populations for hundreds of species through its EAZA ex situ programs (EEPs). EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs.

Do Habitat Restoration Efforts and the Associated Releases of Hatchery‐Reared Fish Affect the Genetic Diversity and Integrity of Native Brown Trout Populations?

Fisheries Management and Ecology, EarlyView.
ABSTRACT Habitat restoration may protect brown trout (Salmo trutta) populations from loss of genetic diversity by increasing environmental carrying capacity and, consequently, population size. However, the accompanying release of hatchery‐reared fish may threaten the genetic integrity of native populations through introgression.

Evaluating Selection Strategies Based on Inbreeding Load via Simulation

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Inbreeding load is the fraction of the mutation load that is due to recessive action of mutations. This load is only expressed in individual's inbred offspring. As such, inbreeding load contributes to genetic heterogeneity among individuals and can thus be used as a criterion of selection.

Impact of inbreeding on production, fertility, and health traits in German Holstein dairy cattle utilizing various inbreeding estimators

Journal of Dairy Science
: In dairy cattle production, it is important to understand how inbreeding affects production, fertility, and health traits. However, there is still limited use of genomic information to estimate inbreeding, despite advancements in genotyping ...

Characterizing Runs of Homozygosity and Inbreeding in American Mink Using SNP Data and Pedigree Information

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Inbreeding increases the likelihood of deleterious recessive alleles becoming homozygous and consequently affecting economically important traits. Runs of homozygosity (ROH), the continuous homozygous segments of the genome and the higher than expected homozygosity (HOM) are genomic indicators of inbreeding, quantified as FROH and FHOM ...
