Artificial selection with traditional or genomic relationships: consequences in coancestry and genetic diversity [PDF]
Frontiers in Genetics, 2015 Estimated breeding values (EBVs) are traditionally obtained from pedigree information. However, EBVs from high-density genotypes can have higher accuracy than EBVs from pedigree information. At the same time, it has been shown that EBVs from genomic data

Controlling Coancestry and Thereby Future Inbreeding by Optimum-Contribution Selection Using Alternative Genomic-Relationship Matrices [PDF]
Frontiers in Genetics, 2020 We tested the consequences of using alternative genomic relationship matrices to predict genomic breeding values (GEBVs) and control of coancestry in optimum contribution selection, where the relationship matrix used to calculate GEBVs was not ...

A note on the rationale for estimating genealogical coancestry from molecular markers [PDF]
Genetics Selection Evolution, 2011 Background Genetic relatedness or similarity between individuals is a key concept in population, quantitative and conservation genetics. When the pedigree of a population is available and assuming a founder population from which the genealogical records ...

Balancing gain and diversity: Optimal contribution selection for sustainable genetic improvement in sugarcane. [PDF]
Plant GenomeAbstract Sugarcane (Saccharum spp. hybrids), the source of ∼80% of the worlds sugar, has experienced a plateau in genetic improvement over recent decades. This stagnation is largely due to the crop's complex polyploid genome and long breeding cycles, which limit the efficiency of traditional selection methods.

Updating the RZooRoH Package for the Analysis of Inbreeding, Identity-By-Descent and Relatedness From Genomic Data. [PDF]
Mol Ecol ResourABSTRACT The RZooRoH R package was implemented to characterize individual inbreeding levels. It identifies DNA segments inherited twice from a common ancestor through different paths, which are known as homozygous‐by‐descent (HBD) segments. The package accepts different data formats and provides multiple outputs: HBD segments, inbreeding rates and ...

Limited Dispersal and Fragmentation-Induced Genomic Erosion in Southern Greater Gliders (<i>Petauroides volans</i>). [PDF]
Ecol EvolUsing genome‐wide SNPs, we characterised population genomic patterns in southern greater gliders from continuous and isolated forests in New South Wales, Australia. Genomic diversity was significantly lower in the isolated population, which exhibited elevated relatedness and a low effective population size, while analyses of fine‐scale spatial genetic ...

Challenging Patterns of Fine-Scale Genetic Structure in Galicia and East-to-West Genetic Divergence Across the Iberian Peninsula-When Technical Batches Rewrite History. [PDF]
FASEB BioadvFindings reported by Bycroft et al. [1] for the Iberian Peninsula, including ultra‐fine population structure in Galicia, East–West genetic differentiation, and North African ancestry associated with the ‘Reconquista’ period, may be influenced by technical artifacts and sampling limitations within the EPICOLON Phase I dataset.

Effect of genomic selection on rate of inbreeding and coancestry and effective population size of Holstein and Jersey cattle populations. [PDF]
, 2020 Genetic diversity in livestock populations is a significant contributor to the sustainability of animal production. Also, genetic diversity allows animal production to become more responsive to environmental changes and market demands.

Animal, 2009 We reasoned that mating animals by minimising the covariance between ancestral contributions (MCAC mating) will generate less inbreeding and at least as much genetic gain as minimum-coancestry mating in breeding schemes where the animals are truncation ...
