Variance9
- Genetic variance is a concept outlined by the English biologist and statistician Ronald Fisher in his fundamental theorem of natural selection. (wikipedia.org)
- In his 1930 book The Genetical Theory of Natural Selection, Fisher postulates that the rate of change of biological fitness can be calculated by the genetic variance of the fitness itself. (wikipedia.org)
- Genetic variance has three major components: the additive genetic variance, dominance variance, and epistatic variance. (wikipedia.org)
- Additive genetic variance involves the inheritance of a particular allele from your parent and this allele's independent effect on the specific phenotype, which will cause the phenotype deviation from the mean phenotype. (wikipedia.org)
- 3. Genetic variance-covariance (G) matrices conveniently summarize the genetic relationships among a suite of traits and are a central parameter in the determination of the multivariate response to selection. (wikipedia.org)
- In particular, trait combinations that form a nearly null genetic subspace with little genetic variance respond only inconsistently to selection. (wikipedia.org)
- 2. Comparing estimates of genetic variance across different relationship models. (wikipedia.org)
- They found that expected genetic variances usually equals the estimated variance times a statistic, Dk, and for the most typical models of relationships, Dk is close to 1, which means most of these models can be used to estimate the genetic variance. (wikipedia.org)
- Epistasis Is a Major Determinant of the Additive Genetic Variance in Mimulus guttatus. (wikipedia.org)

Estimates5
- However, different models may give different estimates of genetic variances. (wikipedia.org)
- In a simulation study, estimates of the effect of a genetic variant were substantially higher when both an endophenotype and an environmental exposure modifying the variant effect were taken into account, particularly under transition models, compared to the alternative of ignoring the endophenotype. (ulaval.ca)
- This study seeks to assess the impact of measurement errors in cumulative exposure on estimates of a gene-environment interaction in a nested case-control study in occupational epidemiology. (bmj.com)
- In simulations, estimates of the gene-environment interaction based on the correctly specified disease model were greatly attenuated and power was diminished appreciably even when errors in exposure were modest. (bmj.com)
- When the "full" mis-specified model was fitted to the simulated data, it yielded erratic estimates. (bmj.com)
Interaction5
- Model coefficients were estimated using generalized estimating equations and were used to derive gene-environment interaction effects and genotype effects at specific levels of exposure. (ulaval.ca)
- We demonstrate this methodology on three published models for each of which we derive the genetic interaction networks and analyze their properties. (researchgate.net)
- Three data analysis strategies were considered: one using a correctly specified disease model (exposure and exposure-gene interaction), and two using mis-specified disease models, one with "gene" as the only risk factor ("gene-only" model) and the other with main effects of both gene and exposure along with their interaction ("full" model). (bmj.com)
- This is illustrated in an analysis of the interaction of cumulative exposure to organophosphate pesticides and paraoxonase gene on the risk of chronic neuropsychological effects among farmers who dip sheep. (bmj.com)
- If "gene" contributes to disease risk only in the presence of exposure, the existence of the gene-environment interaction can be efficiently inferred from a deliberately mis-specified "gene-only" disease model in nested case-control studies. (bmj.com)
