Temporal and region‐specific variations in genome‐wide inbreeding effects on female size and reproduction traits of rainbow trout

open access: yesEvolutionary 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.

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

open access: yesGenetics 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

open access: yesBMC 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

open access: yesAnimals, 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 ...

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

open access: yesBMC 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 ...

On the expected relationship between inbreeding, fitness, and extinction

open access: yesGenetics Selection Evolution, 2006
We assessed the expected relationship between the level and the cost of inbreeding, measured either in terms of fitness, inbreeding depression or probability of extinction. First, we show that the assumption of frequent, slightly deleterious mutations do

ON THE MEASUREMENT OF INBREEDING DEPRESSION [PDF]

open access: yesEvolution, 1994
Theory has shown that the fitness consequences of inbreeding can play a major role in the evolution of sex and reproduction (Maynard Smith 1977; Lloyd 1979; Shields 1982; Kondrashov 1985; Lande and Schemske 1985; Holsinger 1988; Charlesworth et al. 1991; Uyenoyama and Waller 1991 a and references therein).

Effect of recent and ancient inbreeding on production and fertility traits in Canadian Holsteins

open access: yesBMC Genomics, 2020
Background Phenotypic performances of livestock animals decline with increasing levels of inbreeding, however, the noticeable decline known as inbreeding depression, may not be due only to the total level of inbreeding, but rather could be distinctly ...

Predictive Model and Software for Inbreeding-Purging Analysis of Pedigreed Populations

open access: yesG3: Genes, Genomes, Genetics, 2016
The inbreeding depression of fitness traits can be a major threat to the survival of populations experiencing inbreeding. However, its accurate prediction requires taking into account the genetic purging induced by inbreeding, which can be achieved using

Characterizing and Eliminating the Inbreeding Load

open access: yesVeterinary Sciences, 2023
The authors evaluated the relevant literature related to purging, which is the interaction between selection and inbreeding in which the population may eliminate its inbreeding load at least partially. According to the relevant literature, the inbreeding
