An evaluation of inbreeding measures using a whole-genome sequenced cattle pedigree [PDF]

Heredity, 2020
AbstractThe estimation of the inbreeding coefficient (F) is essential for the study of inbreeding depression (ID) or for the management of populations under conservation. Several methods have been proposed to estimate the realizedFusing genetic markers, but it remains unclear which one should be used.

The effect of genomic information on optimal contribution selection in livestock breeding programs [PDF]

, 2013
Long-term benefits in animal breeding programs require that increases in genetic merit be balanced with the need to maintain diversity (lost due to inbreeding). This can be achieved by using optimal contribution selection.

Inbreeding depression for producer-recorded udder, metabolic, and reproductive diseases in US dairy cattle

Journal of Dairy Science
: This study leveraged a growing dataset of producer-recorded phenotypes for mastitis, reproductive diseases (metritis and retained placenta), and metabolic diseases (ketosis, milk fever, and displaced abomasum) to investigate the potential presence of ...

Potential benefit from using an identified major gene in BLUP evaluation with truncation and optimal selection [PDF]

, 1999
This study investigates the benefit of including information on an identified major gene in the estimation of breeding values in BLUP selection programmes. Selection for a quantitative trait is controlled by polygenes and a major locus with known effect.

A rhesus macaque model of α‐dystroglycanopathy caused by a POMT1 splice altering variant

Animal Models and Experimental Medicine, EarlyView.
Rhesus macaques homozygous for a naturally occurring spice altering variant in the POMT1 gene develop lissencephaly, microphthalmia, and muscular contracture. The presentation models severe presentation of the human Walker‐Warburg syndrome. Abstract Background Biallelic mutations in genes associated with α‐dystroglycan glycosylation manifest in a ...

Effect of family relatedness on characteristics of estimated IBD probabilities in relation to precision of QTL estimates

BMC Genetics, 2010
Background A random QTL effects model uses a function of probabilities that two alleles in the same or in different animals at a particular genomic position are identical by descent (IBD).

Population genetic structure analysis of Shall sheep using pedigree information and effect of inbreeding on growth traits

Italian Journal of Animal Science, 2020
The objective of this study was to use pedigree analysis to describe the population structure, genetic variability and inbreeding to quantify their effects on growth traits in Shall sheep.

Pedigree and genome-based patterns of homozygosity in the South African Ayrshire, Holstein, and Jersey breeds

Frontiers in Genetics, 2023
The erosion of genetic diversity limits long-term genetic gain and impedes the sustainability of livestock production. In the South African (SA) dairy industry, the major commercial dairy breeds have been applying estimated breeding values (EBVs) and/or ...

Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak

Animal Research and One Health, EarlyView.
Genetic diversity, adaptation, wild introgression, and coat color mutation of golden yak from two populations on the Qinghai‐Xizang Plateau. ABSTRACT The golden yak lives on the Qinghai‐Xizang Plateau with a golden coat and adapts to high altitudes and strong ultraviolet environment. The golden coat is a prominent phenotype in many domesticated species,

Postcopulatory mechanisms of inbreeding avoidance in the island endemic hihi (Notiomystis cincta) [PDF]

, 2011
Avoiding genetic incompatibility resulting from inbreeding is thought to be one of the main drivers of mate choice, promiscuity, and sexual conflict. Inbreeding avoidance has been found across a wide range of taxa and is predicted to be adaptive when the
