The effect of new and ancestral inbreeding on milk production traits in Iranian Holstein cattle

Journal of Animal Breeding and Genetics, 2023
AbstractInbreeding depression, the reduction of fitness and performance, is due to an increase in the mating of related individuals. Based on the purge hypothesis, inbreeding and breeding over generations reduce the effect of deleterious alleles responsible for inbreeding depression.

grain: a computer program to calculate ancestral and partial inbreeding coefficients using a gene dropping approach [PDF]

open access: yesJournal of Animal Breeding and Genetics, 2015
SummaryGRain is freely available software intended to enable and promote testing of hypotheses with respect to purging and heterogeneity of inbreeding depression. The program is based on a stochastic approach, the gene dropping method, and calculates various coefficients from large and complex pedigrees.

Evaluation of ancestral inbreeding coefficients: Ballou’s formula versus gene dropping

Conservation Genetics, 2006
Estimation of the purging of detrimental effects through inbreeding and selection is an important issue in conservation genetics opening new perspectives for the management of small populations. In 1997 Ballou proposed the ancestral inbreeding coefficient, which is calculated recursively via pedigree inbreeding coefficients, as a tool for evaluating ...

Comparison of ancestral and current-generation inbreeding in an experimental strawberry breeding population

Theoretical and Applied Genetics, 1995
Progenies from first-generation self, half-sib, full-sib, and cross fertilizations were generated to evaluate the magnitude of inbreeding depression for vegetative and production traits in strawberry. Tests were conducted to determine the linearity of trait mean depression with inbreeding rate (ΔF) over this range of inbreeding values, as an indication

Comparison of ancestral, partial, and genomic inbreeding in a local pig breed to achieve genetic diversity

Conservation Genetics Resources, 2018
Inbreeding is omnipresent and unavoidable in population genetics. High levels of inbreeding result in a reduction of genetic diversity and inbreeding depression. The avoidance of inbreeding is a primary goal for the management of small populations and very important for the design of breeding programmes in order to create productive progeny.

A FORTRAN subroutine to compute inbreeding and kinship coefficients according to the number of ancestral generations

Bioinformatics, 1989
This paper presents a FORTRAN IV subroutine to calculate inbreeding and kinship coefficients from pedigree information in a diploid population without self-fertilization. The user can specify the number of ancestral generations to be taken into account. It is thus possible to determine contributions of succeeding ancestral generations to the inbreeding

Estimation of ancestral inbreeding effects on stillbirth, calving ease and birthweight in German Holstein dairy cattle

Journal of Animal Breeding and Genetics, 2014
SummaryIn this study, the effect of different measurements of ancestral inbreeding on birthweight, calving ease and stillbirth were analysed. Three models were used to estimate the effect of ancestral inbreeding, and the estimated regression coefficient of phenotypic data on different measurements of ancestral inbreeding was used to quantify the effect
