Heritability and Genetic Variance Components in Sunflower Single Cross Hybrids [PDF]
Journal of Agricultural Science and Sustainable Production, 2015 In order to estimate genetic parameters in 16 Sunflower single cross hybrids obtained from crossing of 4 cytoplasmic male sterile and 4 fertility restorer lines, a North Carolina Design II was conducted using RCBD design with 3 replications at Khoy ...

Genetic linkage analysis using lognormal variance components [PDF]
Annals of Human Genetics, 1998 Typically genetic studies of continuous traits such as cholesterol levels or blood pressure assume that interindividual variability follows a normal distribution. Here we develop methods to analyze positively skewed data by assuming a lognormal distribution.

The genetic basis of inheritance of plant height in maize [PDF]
Journal of Agricultural Sciences (Belgrade), 2015 The aim of this study, on the grounds of direct and reciprocal diallel crossing of five inbred lines of maize, was to determine: variability, heterosis, combining ability and genetic basis of plant height inheritance. The experiment was based on

Modeling methylation data as an additional genetic variance component [PDF]
BMC Proceedings, 2018 High-throughput platforms allow the characterization of thousands of previously known methylation sites. These platforms have great potential for investigating the epigenetic effects that are partially responsible for gene expression control. Methylation sites provide a bridge for the investigation of real-time environmental contributions on genomic ...

Variance components genetic association test for zero‐inflated count outcomes [PDF]
Genetic Epidemiology, 2018 AbstractCommonly in biomedical research, studies collect data in which an outcome measure contains informative excess zeros; for example, when observing the burden of neuritic plaques (NPs) in brain pathology studies, those who show none contribute to our understanding of neurodegenerative disease.

Quantitative Genetic Variance Maintained by Fluctuating Selection with Overlapping Generations: Variance Components and Covariances [PDF]
Evolution, 1997 The quantitative genetic variance-covariance that can be maintained in a random environment is studied, assuming overlapping generations and Gaussian stabilizing selection with a fluctuating optimum. The phenotype of an individual is assumed to be determined by additive contributions from each locus on paternal and maternal gametes (i.e., no epistasis ...

Animals, 2021 It is widely known that the environment influences phenotypic expression and that its effects must be accounted for in genetic evaluation programs. The most used method to account for environmental effects is to add herd and contemporary group to the ...

Two variance component model improves genetic prediction in family data sets [PDF]
The American Journal of Human Genetics, 2015 AbstractGenetic prediction based on either identity by state (IBS) sharing or pedigree information has been investigated extensively using Best Linear Unbiased Prediction (BLUP) methods. Such methods were pioneered in the plant and animal breeding literature and have since been applied to predict human traits with the aim of eventual clinical utility ...
