Animals, 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

An effective rotational mating scheme for inbreeding reduction in captive populations illustrated by the rare sheep breed [PDF]
, 2008 Within breeds and other captive populations, the risk of high inbreeding rates and loss of diversity can be high within (small) herds or subpopulations.

The existence of species rests on a metastable equilibrium between inbreeding and outbreeding [PDF]

Genomic signatures of inbreeding in a critically endangered parrot, the kākāpō
G3, 2021 Events of inbreeding are inevitable in critically endangered species. Reduced population sizes and unique life-history traits can increase the severity of inbreeding, leading to declines in fitness and increased risk of extinction.

Prediction of genetic gain from quadratic optimisation with constrained rates of inbreeding [PDF]
, 2006 There are selection methods available that allow the optimisation of genetic contributions of selection candidates for maximising the rate of genetic gain while restricting the rate of inbreeding. These methods imply selection on quadratic indices as the

Predictive Model and Software for Inbreeding-Purging Analysis of Pedigreed Populations
G3: Genes, Genomes, Genetics, 2016 The inbreeding depression of fitness traits can be a major threat to the survival of populations experiencing inbreeding. However, its accurate prediction requires taking into account the genetic purging induced by inbreeding, which can be achieved using

Quantitative genetics model as the unifying model for defining genomic relationship and inbreeding coefficient. [PDF]
PLoS ONE, 2014 The traditional quantitative genetics model was used as the unifying approach to derive six existing and new definitions of genomic additive and dominance relationships.

Inbreeding and selection on sex ratio in the bark beetle Xylosandrus germanus [PDF]
, 2011 Background: Local Mate Competition (LMC) theory predicts a female should produce a more female-biased sex ratio if her sons compete with each other for mates.

Strategies for controlling rates of inbreeding in MOET nucleus schemes for beef cattle [PDF]
, 1994 A closed MOET (multiple ovulation and embryo transfer) nucleus scheme, with overlapping generations, was modelled for beef cattle by stochastic simulation. Selection was carried out for 25 years on a trait measurable in both sexes and with a heritability

Crop science, 2019 Pedigree maps are useful for germplasm exploration and identification of genetic bottlenecks. The primary objective of this study was to construct pedigree maps for red clover (Trifolium pratense L.) accessions held in the Margot Forde Germplasm Centre ...
