Epistasis and its contribution to genetic variance components. [PDF]
Genetics, 1995 Abstract We present a new parameterization of physiological epistasis that allows the measurement of epistasis separate from its effects on the interaction (epistatic) genetic variance component. Epistasis is the deviation of two-locus genotypic values from the sum of the contributing single-locus genotypic values.

Revista Brasileira de Zootecnia, 2012 The objective of this research was to compare the magnitude of genetic parameters (coefficients of heritability and genetic correlation) as estimated by the Restricted Maximum Likelihood (REML) method and Bayesian Inference, and to estimate the genetic ...

Components of Genetic Variance in Milk Yield
Journal of Dairy Science, 1969 Abstract The purpose of this research was to determine the importance of non-additive genetic effects and genetic maternal effects in the inheritance of milk production in dairy cattle. Expressing milk yield as a deviation from herdmate average eliminated most of the variation due to herds, years, seasons, and their interactions without affecting the

Genetic (co)variance components for slaughter traits in a multi-breed sheep population
Animal, 2023 Carcass value is one of the main contributors to revenue in meat sheep enterprises, while age at slaughter is also a major component to the cost of production.

Genetic imprinting analysis for alcoholism genes using variance components approach [PDF]
BMC Genetics, 2005 Abstract Genomic imprinting, which is also known as the parent-of-origin effect, is a mechanism that only expresses one copy of a gene pair depending upon the parental origin. Although many chromosomal regions in the human genome are likely to be imprinted, imprinting is not accounted for in the usual linkage analysis.

Maternal effect on sports performance traits in horses
Czech Journal of Animal Science, 2019 The aim of the study was to estimate the direct additive genetic effect and the additive maternal effect on the level of traits estimated during the Polish Jumping Championships for Young Horses.

The Genetic Architecture of Quantitative Traits Cannot Be Inferred from Variance Component Analysis. [PDF]
PLoS Genetics, 2016 Classical quantitative genetic analyses estimate additive and non-additive genetic and environmental components of variance from phenotypes of related individuals without knowing the identities of quantitative trait loci (QTLs). Many studies have found a

Semiparametric variance components models for genetic studies with longitudinal phenotypes [PDF]
Biostatistics, 2012 In a family-based genetic study such as the Framingham Heart Study (FHS), longitudinal trait measurements are recorded on subjects collected from families. Observations on subjects from the same family are correlated due to shared genetic composition or environmental factors such as diet.

Epistasis Is a Major Determinant of the Additive Genetic Variance in Mimulus guttatus. [PDF]
PLoS Genetics, 2015 The influence of genetic interactions (epistasis) on the genetic variance of quantitative traits is a major unresolved problem relevant to medical, agricultural, and evolutionary genetics.

Animals, 2023 Monitoring the genetic variance of traits is a key priority to ensure the sustainability of breeding programmes in populations under directional selection, since directional selection can decrease genetic variation over time.
