Evaluating the selection of improved Fars native fowl with the inbreeding assessment approach [PDF]

پژوهش های علوم دامی, 2022
Introduction: Performance of native fowl can be improved by making changes in feeding, rearing and health issues. Genetic improvement of these breeds can be achieved through the breeding programs such as selection, crossbreeding, or both.

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.

Genetic inbreeding depression load for morphological traits and defects in the Pura Raza Española horse

Genetics Selection Evolution, 2020
Background Inbreeding is caused by mating between related individuals and is associated with reduced fitness and performance (inbreeding depression). Several studies have detected heterogeneity in inbreeding depression among founder individuals. Recently,

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.

Sensitive males: inbreeding depression in an endangered bird [PDF]

, 2010
Attempts to conserve threatened species by establishing new populations via reintroduction are controversial. Theory predicts that genetic bottlenecks result in increased mating between relatives and inbreeding depression.

Inbreeding depression due to recent and ancient inbreeding in Dutch Holstein–Friesian dairy cattle

Genetics Selection Evolution, 2019
Background Inbreeding decreases animal performance (inbreeding depression), but not all inbreeding is expected to be equally harmful. Recent inbreeding is expected to be more harmful than ancient inbreeding, because selection decreases the frequency of ...

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 ...

Inbreeding Depression and Purging for Meat Performance Traits in German Sheep Breeds

Animals, 2023
This study provides estimates on genetic parameters, inbreeding depression and purging for meat performance measures from 25 German sheep breeds. All German meat, merino sheep breeds and breeds of other breeding directions with a sufficient number of ...

Pedigree error due to extra-pair reproduction substantially biases estimates of inbreeding depression [PDF]

, 2013
Understanding the evolutionary dynamics of inbreeding and inbreeding depression requires unbiased estimation of inbreeding depression across diverse mating systems.

Postcopulatory mechanisms of inbreeding avoidance in the island endemic hihi (Notiomystis cincta) [PDF]

, 2011
Avoiding genetic incompatibility resulting from inbreeding is thought to be one of the main drivers of mate choice, promiscuity, and sexual conflict. Inbreeding avoidance has been found across a wide range of taxa and is predicted to be adaptive when the
