Variance components,heritability estimates,and breeding values for performance test traits in Old Kladruber horses
harness horse genetic parameters performance test genetic resource
2016/9/1
The Old Kladruber horse is an important Czech genetic resource. In the current study, two categories of traits were evaluated – the first, a numerical score for Type and Gender Expression and the seco...
Methods of variance component estimation
one-way ANOVA ANOVA-method MINQUE MIVQUE Bayesian approach Gibbs sampling numerical example
2015/6/2
Estimation of variance components is a method often used in population genetics and applied in animal breeding. Even experienced population geneticists nowadays feel lost if confronted with the huge s...
Which factors explain lepidopteran larvae variance in seasonal guilds on some oaks?
cluster analysis DCA history-life traits of lepidopteran larvae oaks seasonal guilds
2015/3/20
Differences between the oak lepidopteran communities were studied in Slovakia in 1993 and 1994. Sampling was undertaken between April and October on 3 oak species. Biological traits of larvae were exa...
Mixed model with spatial variance–covariance structure for accommodating of local stationary trend and its influence on multi-environmental crop variety trial assessment
consistency ratio test wheat barley
2014/10/23
The most common procedure for analyzing multi-environmental trials is based on the assumption that the residual error variance is homogenous across all locations considered. However, this may often be...
A multivariate analysis of variance (MANOVA) of the performance of sorghum lines in different agro-ecological regions of Zimbabwe
Multi-environment MANOVA resettled farmers sorghum production
2010/2/4
This study presents a multi-environment trial to evaluate the performance of sorghum lines in a target population of environments in Zimbabwe. The study attempts to determine whether genotypic variati...
Mapping of the Porcine Calpastatin Gene and Association Study of Its Variance with Economic Traits in Pigs
Calpastatin (CAST) Linkage Mapping QTL Mapping Korean Native Pig
2006/4/21
The objectives of this study were to confirm a location of the calpastatin (CAST) gene in chromosome 2 and to detect associations of genetic variations with economic traits in the porcine CAST gene as...
Variance Component Estimates with Dominance Models for Milk Production in Holsteins of Japan Using Method R
Method R Additive Variance Dominance Variance Sire by Herd Interaction Inbreeding Depression Milk Production, Holstein
2006/4/21
Fractions of herd-year-season, sire by herd interaction, additive genetic and dominance genetic variances were estimated for milk production traits in Holsteins of Japan using Method R. Inbreeding dep...
Investigation of Biases for Variance Components on Multiple Traits with Varying Number of Categories in Threshold Models Using Bayesian Inferences
Categorical Traits Bayesian Variance Components Biases
2002/4/11
Gibbs sampling algorithms were implemented to the multi-trait threshold animal models with any combinations of multiple binary, ordered categorical, and linear traits and investigate the amount of bia...
