Genomic and fitness consequences of inbreeding in an endangered carnivore [PDF]

Molecular Ecology, 2021
AbstractReduced fitness through genetic drift and inbreeding is a major threat to small and isolated populations. Although previous studies have generally used genetically verified pedigrees to document effects of inbreeding and gene flow, these often fail to capture the whole inbreeding history of the species.

Genome-wide assessment and mapping of inbreeding depression identifies candidate genes associated with semen traits in Holstein bulls

BMC Genomics, 2023
Background The reduction in phenotypic performance of a population due to mating between close relatives is called inbreeding depression. The genetic background of inbreeding depression for semen traits is poorly understood.

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.

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

, 2013
BACKGROUND: 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. The availability of

Efficient genome ancestry inference in complex pedigrees with inbreeding [PDF]

Bioinformatics, 2010
Abstract Motivation: High-density SNP data of model animal resources provides opportunities for fine-resolution genetic variation studies. These genetic resources are generated through a variety of breeding schemes that involve multiple generations of matings derived from a set of founder animals.

Survival and divergence in a small group: The extraordinary genomic history of the endangered Apennine brown bear stragglers [PDF]

, 2017
About 100 km east of Rome, in the central Apennine Mountains, a critically endangered population of ∼50 brown bears live in complete isolation. Mating outside this population is prevented by several 100 km of bear-free territories.

A method for genotyping elite breeding stocks of leaf chicory (Cichorium intybus L.) by assaying mapped microsatellite marker loci [PDF]

, 2015
BACKGROUND: Leaf chicory (Cichorium intybus subsp. intybus var. foliosum L.) is a diploid plant species (2n = 18) of the Asteraceae family. The term "chicory" specifies at least two types of cultivated plants: a leafy vegetable, which is highly ...

Management of Genetic Diversity in the Era of Genomics

Frontiers in Genetics, 2020
Management of genetic diversity aims to (i) maintain heterozygosity, which ameliorates inbreeding depression and loss of genetic variation at loci that may become of importance in the future; and (ii) avoid genetic drift, which prevents deleterious ...

Short communication: Methods to compute genomic inbreeding for ungenotyped individuals [PDF]

Journal of Dairy Science, 2020
The genomic measure of inbreeding is closer to the actual inbreeding than the pedigree-based measure. However, it cannot be computed for ungenotyped animals. An estimate of genomic inbreeding comes from the diagonal of matrix H used in single-step methods. This matrix projects genomic relationships to all ungenotyped members of the pedigree.
