Homozygosity and risk of childhood death due to invasive bacterial disease. [PDF]

, 2009
BACKGROUND: Genetic heterozygosity is increasingly being shown to be a key predictor of fitness in natural populations, both through inbreeding depression, inbred individuals having low heterozygosity, and also through chance linkage between a marker and

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 ...

Inbreeding depression for kit survival at birth in a rabbit population under long-term selection

Genetics Selection Evolution, 2020
Background Accumulation of detrimental mutations in small populations leads to inbreeding depression of fitness traits and a higher frequency of genetic defects, thus increasing risk of extinction.

Sex-specific inbreeding depression: A meta-analysis

, 2022
Inbreeding depression, the reduced fitness of the offspring of related individuals, can affect males and females differently. Although a comprehensive theoretical framework describing the causes of sex-specific inbreeding depression is lacking, empirical

Can age‐related changes in parental care modulate inbreeding depression? A test using the burying beetle, Nicrophorus orbicollis

Ecology and Evolution, 2022
Parental care has been shown to reduce the magnitude of inbreeding depression in some species with facultative care. However, parents often vary in the quality or amount of care they provide to their offspring, and it is less clear whether this variation

Effect of Individual Rate of Inbreeding, Recent and Ancestral Inbreeding on Wool Quality, Muscling Conformation and Exterior in German Sheep Breeds

Animals, 2023
This study provides comprehensive results on the current status of inbreeding depression for traits upon which sheep are selected for the herdbook in Germany. A total of 30 sheep breeds from the OviCap national database met the inclusion criteria for the

Data from: Inbreeding, inbreeding depression and infidelity in a cooperatively-breeding bird [PDF]

, 2018
Inbreeding depression plays a major role in shaping mating systems: in particular, inbreeding avoidance is often proposed as a mechanism explaining extra-pair reproduction in socially-monogamous species.

Inbreeding depression in livestock: comparing trait groups and inbreeding measures

, 2022
Inbreeding depression has been documented for many livestock populations. We compared inbreeding depression estimates (1) between trait groups, and (2) between different pedigree-based and genomic inbreeding measures.

A multivariate analysis with direct additive and inbreeding depression load effects

Genetics Selection Evolution, 2019
Background Inbreeding is caused by mating between related individuals and its most common consequence is inbreeding depression. Several studies have detected heterogeneity in inbreeding depression among founder individuals, and recently a procedure for ...

Variance component analysis of skin and weight data for sheep subjected to rapid inbreeding [PDF]

, 1999
A variance component analysis was carried out on data from a 20-year experiment in the rapid inbreeding of purebred and crossbred lines of three hill breeds of sheep.
