Effect of genomic selection and genotyping strategy on estimation of variance components in animal models using different relationship matrices

Genetics Selection Evolution, 2020
Background The traditional way to estimate variance components (VC) is based on the animal model using a pedigree-based relationship matrix (A) (A-AM).

Estimation and consequences of direct-maternal genetic and environmental covariances in models for genetic evaluation in broilers

Genetics Selection Evolution, 2023
Background Maternal effects influence juvenile traits such as body weight and early growth in broilers. Ignoring significant maternal effects leads to reduced accuracy and inflated predicted breeding values.

Pre-selection against a lethal recessive allele in breeding schemes with optimum-contribution selection or truncation selection

Genetics Selection Evolution, 2021
Background We tested the hypothesis that breeding schemes with a pre-selection step, in which carriers of a lethal recessive allele (LRA) were culled, and with optimum-contribution selection (OCS) reduce the frequency of a LRA, control rate of inbreeding,

Large-scale association study on daily weight gain in pigs reveals overlap of genetic factors for growth in humans

BMC Genomics, 2022
Background Imputation from genotyping array to whole-genome sequence variants using resequencing of representative reference populations enhances our ability to map genetic factors affecting complex phenotypes in livestock species.

Genomic prediction using a reference population of multiple pure breeds and admixed individuals

Genetics Selection Evolution, 2021
Background In dairy cattle populations in which crossbreeding has been used, animals show some level of diversity in their origins. In rotational crossbreeding, for instance, crossbred dams are mated with purebred sires from different pure breeds, and ...

The impact of genotyping strategies and statistical models on accuracy of genomic prediction for survival in pigs

Journal of Animal Science and Biotechnology, 2023
Background Survival from birth to slaughter is an important economic trait in commercial pig productions. Increasing survival can improve both economic efficiency and animal welfare. The aim of this study is to explore the impact of genotyping strategies

Accounting for genetic interactions improves modeling of individual quantitative trait phenotypes in yeast. [PDF]

, 2016
Experiments in model organisms report abundant genetic interactions underlying biologically important traits, whereas quantitative genetics theory predicts, and data support, the notion that most genetic variance in populations is additive.

QUANTITATIVE GENETICS OF HETEROCHRONY [PDF]

Evolution, 1987
A model of quantitative-genetic variation in developmental processes is introduced and analyzed. The model is of a bifurcating sequence of events in which traits develop from the same tissue until a transition occurs, after which they develop partially independently.

Theory and Practice in Quantitative Genetics [PDF]

, 2003
With the rapid advances in molecular biology, the near completion of the human genome, the development of appropriate statistical genetic methods and the availability of the necessary computing power, the identification of quantitative trait loci has now

Transcriptomic and presence/absence variation in the barley genome assessed from multi-tissue mRNA sequencing and their power to predict phenotypic traits

BMC Genomics, 2019
Background Barley is the world’s fourth most cultivated cereal and is an important crop model for genetic studies. One layer of genomic information that remains poorly explored in barley is presence/absence variation (PAV), which has been suggested to ...
