A Practical Application of Genomic Predictions for Mastitis Resistance in Italian Holstein Heifers

Animals, 2022
Heifers are a fundamental resource on farms, and their importance is reflected in both farm management and economy. Therefore, the selection of heifers to be reared on a farm should be carefully performed to select only the best animals.

Emerging issues in genomic selection [PDF]

Journal of Animal Science, 2021
Abstract Genomic selection (GS) is now practiced successfully across many species. However, many questions remain, such as long-term effects, estimations of genomic parameters, robustness of genome-wide association study (GWAS) with small and large datasets, and stability of genomic predictions.

Functional Allium fistulosum Centromeres Comprise Arrays of a Long Satellite Repeat, Insertions of Retrotransposons and Chloroplast DNA

Frontiers in Plant Science, 2020
The centromere is a unique part of the chromosome combining a conserved function with an extreme variability in its DNA sequence. Most of our knowledge about the functional centromere organization is obtained from species with small and medium genome ...

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

Genomic selection in rubber tree breeding: A comparison of models and methods for managing G×E interactions [PDF]

, 2019
Several genomic prediction models combining genotype × environment (G×E) interactions have recently been developed and used for genomic selection (GS) in plant breeding programs. G×E interactions reduce selection accuracy and limit genetic gains in plant

On the Accuracy of Genomic Selection

PLOS ONE, 2016
Genomic selection is focused on prediction of breeding values of selection candidates by means of high density of markers. It relies on the assumption that all quantitative trait loci (QTLs) tend to be in strong linkage disequilibrium (LD) with at least one marker.

Genomic selection using different marker types and densities [PDF]

, 2008
With the availability of high-density marker maps and cost-effective genotyping, genomic selection methods may provide faster genetic gain than can be achieved by current selection methods based on phenotypes and the pedigree. Here we investigate some of

Comparing Genomic Prediction Models by Means of Cross Validation

Frontiers in Plant Science, 2021
In the two decades of continuous development of genomic selection, a great variety of models have been proposed to make predictions from the information available in dense marker panels.

The Adaptive Significance of Natural Genetic Variation in the DNA Damage Response of Drosophila melanogaster. [PDF]

, 2016
Despite decades of work, our understanding of the distribution of fitness effects of segregating genetic variants in natural populations remains largely incomplete. One form of selection that can maintain genetic variation is spatially varying selection,

Detection of selection signatures in dairy and beef cattle using high-density genomic information [PDF]

, 2015
peer-reviewedBackground Artificial selection for economically important traits in cattle is expected to have left distinctive selection signatures on the genome. Access to high-density genotypes facilitates the accurate identification of
