THI Modulation of Genetic and Non-genetic Variance Components for Carcass Traits in Hanwoo Cattle [PDF]

open access: yesFrontiers in Genetics, 2020
The phenotype of carcass traits in beef cattle are affected by random genetic and non-genetic effects, which both can be modulated by an environmental variable such as Temperature-Humidity Index (THI), a key environmental factor in cattle production.

Predicting the purebred-crossbred genetic correlation from the genetic variance components in the parental lines [PDF]

open access: yesGenetics Selection Evolution, 2021
Background The genetic correlation between purebred and crossbred performance ( $${r}_{pc}$$ r pc ) is an important parameter in pig and poultry breeding, because response to selection in crossbred performance depends on the value of $${r}_{pc}$$ r pc ...

Contribution of genetic effects to genetic variance components with epistasis and linkage disequilibrium [PDF]

open access: yesBMC Genetics, 2009
Background Cockerham genetic models are commonly used in quantitative trait loci (QTL) analysis with a special feature of partitioning genotypic variances into various genetic variance components, while the F∞ genetic models are widely used in genetic ...

Analysis of variance components for genetic markers with unphased genotypes [PDF]

open access: yesFrontiers in Genetics, 2016
An ANOVA type general multi-allele (GMA) model was proposed in cite{Wang2014} on analysis of variance components for quantitative trait loci or genetic markers with phased or unphased genotypes.

Genetic variance components of the growth curve for Isfahan indigenous chicken [PDF]

open access: yesVeterinary Medicine and Science
Background Being able to model a growth curve using three or four non‐linear functional parameters could help explain the growth phenomenon in a precise way and would allow the comparison of an animal's development rate, optimize management and feeding ...

Estimates for genetic variance components in reciprocal recurrent selection in populations derived from maize single-cross hybrids. [PDF]

open access: yesScientificWorldJournal, 2014
This study was carried out to obtain the estimates of genetic variance and covariance components related to intra- and interpopulation in the original populations (C0) and in the third cycle (C3) of reciprocal recurrent selection (RRS) which allows ...

Using the realized relationship matrix to disentangle confounding factors for the estimation of genetic variance components of complex traits [PDF]

open access: yesGenetics Selection Evolution, 2010
Background In the analysis of complex traits, genetic effects can be confounded with non-genetic effects, especially when using full-sib families. Dominance and epistatic effects are typically confounded with additive genetic and non-genetic effects ...

QTLRel: an R Package for Genome-wide Association Studies in which Relatedness is a Concern

open access: yesBMC Genetics, 2011
Background Existing software for quantitative trait mapping is either not able to model polygenic variation or does not allow incorporation of more than one genetic variance component. Improperly modeling the genetic relatedness among subjects can result

Dissecting total genetic variance into additive and dominance components of purebred and crossbred pig traits

open access: yesAnimal, 2019
The partition of the total genetic variance into its additive and non-additive components can differ from trait to trait, and between purebred and crossbred populations.
