Purging of inbreeding depression within the Irish Holstein-Friesian population

open access: yesGenetics Selection Evolution, 2009
The objective of this study was to investigate whether inbreeding depression in milk production or fertility performance has been partially purged due to selection within the Irish Holstein-Friesian population.

Commonly used genomic estimators of individual inbreeding in livestock

open access: yesCzech Journal of Animal Science
: Management of inbreeding is one of the crucial parts of breeding programs in livestock populations. Traditionally, the inbreeding coefficient is calculated using pedigree data; however, it can also be estimated from genomic data.

Estimation of Inbreeding Coefficient and Its Effects on Lamb Survival in Sheep

open access: yesپژوهشهای علوم دامی ایران, 2016
Introduction The mating of related individuals produces an inbred offspring and leads to an increased homozygosity in the progeny, genetic variance decrease within families and increase between families.

Rank-invariant estimation of inbreeding coefficients [PDF]

open access: yesHeredity, 2021
AbstractThe two alleles an individual carries at a locus are identical by descent (ibd) if they have descended from a single ancestral allele in a reference population, and the probability of such identity is the inbreeding coefficient of the individual.

Ballou's Ancestral Inbreeding Coefficient: Formulation and New Estimate with Higher Reliability. [PDF]

open access: yesAnimals (Basel)
Inbreeding is unavoidable in small populations. However, the deleterious effects of inbreeding on fitness-related traits (inbreeding depression) may not be an inevitable phenomenon, since deleterious recessive alleles causing inbreeding depression might ...

The inbreeding coefficients of the Hadza

open access: yesAnnals of Human Biology, 1977
A systematic tabulation is provided of the frequency of different types of inbreeding in the Hadza. Genealogical information was obtained for 931 individuals, alive and dead. Inbreeding was encountered with 165 individuals. There were 49 different types of inbred genealogy.

Genetic diversity and inbreeding in the Greek Skyros horse [PDF]

open access: yes, 2008
Inbreeding and heterozygosity levels were calculated in a population of 77 horses of the endangered Skyros breed that had been raised since 1988 at an experimental farm. Twenty one horses were inbred with average inbreeding coefficient of 0.11 (+/-0.02).

Pedigree analysis and inbreeding effects over morphological traits in Campolina horse population

open access: yesAnimal, 2018
Genetic improvement, without control of inbreeding, can go to loss of genetic variability, reducing the potential for genetic gains in the domestic populations.
