Genomic consequences of intensive inbreeding in miniature inbred pigs

BMC Genomics
Background Inbreeding, a central theme in evolutionary and conservation biology, is a crucial practice in breeding to stabilize and enhance the specific traits or to establish inbred lines.

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.

Genomic partitioning of inbreeding depression in humans [PDF]

The American Journal of Human Genetics, 2021
Across species, offspring of related individuals often exhibit significant reduction in fitness-related traits, known as inbreeding depression (ID), yet the genetic and molecular basis for ID remains elusive. Here, we develop a method to quantify enrichment of ID within specific genomic annotations and apply it to human data.

Genomic and fitness consequences of inbreeding in an endangered carnivore [PDF]

Molecular Ecology, 2021
AbstractReduced fitness through genetic drift and inbreeding is a major threat to small and isolated populations. Although previous studies have generally used genetically verified pedigrees to document effects of inbreeding and gene flow, these often fail to capture the whole inbreeding history of the species.

Genomic signatures of inbreeding in a critically endangered parrot, the kākāpō [PDF]

G3 Genes|Genomes|Genetics, 2021
Abstract Events of inbreeding are inevitable in critically endangered species. Reduced population sizes and unique life-history traits can increase the severity of inbreeding, leading to declines in fitness and increased risk of extinction. Here, we investigate levels of inbreeding in a critically endangered flightless parrot, the kākāpō

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.

Genomic Inbreeding and Runs of Homozygosity Analysis of Cashmere Goat. [PDF]

Animals (Basel)
Cashmere goats are valuable genetic resources which are famous worldwide for their high-quality fiber. Runs of homozygosity (ROHs) have been identified as an efficient tool to assess inbreeding level and identify related genes under selection. However, there is limited research on ROHs in cashmere goats.

Genomic consequences of isolation and inbreeding in an island dingo population

Genome Biology and Evolution, 2023
ABSTRACT Dingoes come from an ancient canid lineage that originated in East Asia around 8000-11,000 years BP. As Australia’s largest terrestrial predator, dingoes play an important ecological role. A small, protected population exists on a world heritage listed offshore island, K’gari (formerly Fraser Island).

Genomics advances the study of inbreeding depression in the wild [PDF]

Evolutionary Applications, 2016
AbstractInbreeding depression (reduced fitness of individuals with related parents) has long been a major focus of ecology, evolution, and conservation biology. Despite decades of research, we still have a limited understanding of the strength, underlying genetic mechanisms, and demographic consequences of inbreeding depression in the wild.

The genome of the Pyrenean desman and the effects of bottlenecks and inbreeding on the genomic landscape of an endangered species [PDF]

Evolutionary Applications, 2021
Abstract The Pyrenean desman ( Galemys pyrenaicus ) is a small semiaquatic mammal endemic to the Iberian Peninsula. Despite its limited range, this species presents a strong genetic structure due to past isolation in glacial refugia and subsequent bottlenecks.
