GENETIC VARIANCE COMPONENTS IN CULTIVATED STRAWBERRY

Canadian Journal of Genetics and Cytology, 1970
Two methods of determining the relative importance of the additive, dominance and epistatic components of genetic variance indicated that the nonadditive variance (most of which was shown to be epistatic) constituted approximately 50% of the total genetic variance for 20 commercial characteristics of the cultivated strawberry.

Deriving components of genetic variance for multilocus models

Genetic Epidemiology, 1997
Several authors have considered two-locus models as a basis for the inheritance of complex diseases. The purpose of this paper is to give a simple general formulation to derive the additive, dominant, and epistatic effects, and hence the corresponding variance components, for any multilocus model.

A note on genetic variance components in mixed models

Genetic Epidemiology, 2003
AbstractBurton et al. ([1999] Genet. Epidemiol. 17:118–140) proposed a series of generalized linear mixed models for pedigree data that account for residual correlation between related individuals. These models may be fitted using Markov chain Monte Carlo methods, but the posterior mean for small variance components can exhibit marked positive bias ...

Application of approximate variances of variance components and their ratios in genetic tests

Theoretical and Applied Genetics, 1995
The application and underlying assumptions of formulae used to estimate the variance of variance components and ratios of variance components are fully described for (1) variance components estimated using Henderson's Method 3 (HM3) and Restricted Maximum Likelihood (REML) and (2) ratios of variance components commonly used in genetic tests - biased ...

The Analytic Identification of Variance Component Models Common to Behavior Genetics

Behavior Genetics, 2021
Many behavior genetics models follow the same general structure. We describe this general structure and analytically derive simple criteria for its identification. In particular, we find that variance components can be uniquely estimated whenever the relatedness matrices that define the components are linearly independent (i.e., not confounded).

Comparative Studies on the Estimation of Genetic Variances by Several Variance Components Estimation Method

Biometrical Journal, 1982
AbstractUsing a quantitative genetic model, this paper compares four different methods for estimating genetic variance components. Given various genetic parameters, data were generated and estimates computed. The number of negative estimates, the sample mean, the sample variance, and the sample mean squared error were computed for each method.
