Inferences About Inbreeding Depression Based on Changes of the Inbreeding Coefficient [PDF]

open access: yesEvolution, 1990
In a mixed-mating population, the fitness of selfed individuals, relative to outcrossed individuals, can be estimated from observed changes of the inbreeding coefficient F. In general, three measurements of F, or two measurements of F and one of the selfing rate, spanning two generations are needed.

Inbreeding-Driven Innate Behavioral Changes in Drosophila melanogaster

open access: yesBiology, 2023
Drosophila melanogaster has long been used to demonstrate the effect of inbreeding, particularly in relation to reproductive fitness and stress tolerance. In comparison, less attention has been given to exploring the influence of inbreeding on the innate

Genetic Diversity and the Impact of the Breed Proportions of US Brown Swiss in German Brown Cattle

open access: yesAnimals, 2021
Increase of inbreeding and loss of genetic diversity have large impact on farm animal genetic resources. Therefore, the aims of the present study were to analyse measures of genetic diversity as well as recent and ancestral inbreeding using pedigree data

An empirical evaluation of the estimation of inbreeding depression from molecular markers under suboptimal conditions

open access: yesEvolutionary Applications, 2023
Inbreeding depression (ID), the reduction in fitness due to inbreeding, is typically measured by the regression of the phenotypic values of individuals for a particular trait on their corresponding inbreeding coefficients (F).

Inbreeding evaluation using microsatellite confirmed inbreeding depression in growth in the Fenneropenaeus chinensis natural population

open access: yesFrontiers in Genetics, 2023
Understanding inbreeding depressions (IBDs), the effect on the phenotypic performance of inbreeding, is of major importance for evolution and conservation genetics.

A Spectral Theory for Wright’s Inbreeding Coefficients and Related Quantities [PDF]

open access: yesPLOS Genetics, 2020
Abstract Wright’s inbreeding coefficient, F ST , is a fundamental measure in population genetics. Assuming a predefined population subdivision, this statistic is classically used to evaluate population structure at a given genomic locus. With large numbers of loci,

INBREEDING AND INBREEDING DEPRESSION IN SLOVENIAN HOLSTEIN POPULATION [PDF]

open access: yesPoljoprivreda, 2007
Analysis of inbreeding and inbreeding depression was done on the data of routine breeding value estimation for milk production data on Holstein population in Slovenia.

Using Pedigree and Genomic Data toward Better Management of Inbreeding in Italian Dairy Sheep and Goat Breeds

open access: yesAnimals, 2022
The inbreeding coefficient is an important parameter for livestock management. Small ruminant breeders and associations mainly rely on pedigree information, but genomic tools are gaining relevance, overcoming possible pedigree inconsistencies. This study

Inbreeding and fertility in Irish Wolfhounds in Sweden: 1976 to 2007

open access: yesActa Veterinaria Scandinavica, 2009
Background Given that no influence of inbreeding on life expectancy could be demonstrated in Irish Wolfhounds in a previous study, it was decided to test the influence of inbreeding and other parameters on fertility in this breed.

Simultaneous Estimation of Null Alleles and Inbreeding Coefficients [PDF]

open access: yesJournal of Heredity, 2008
Although microsatellites are a very efficient tool for many population genetics applications, they may occasionally produce "null" alleles, which, when present in high proportion, may affect estimates of key parameters such as inbreeding and relatedness coefficients or measures of genetic differentiation.
