SOME GENETIC PARAMETERS, HERITABILITY AND GENETIC RESULTANT AS AFFECTED BY GENOTYPES AND POPULATIONS IN SUNFLOWER. [PDF]
To know the genetic variations for some sunflower (Helianthus annuus L.) traits under the influence of three plant population (40000, 50000 and 60000 plants.ha-1) to tow varieties (oil and non-oil) of sunflower.

Partitioning Phenotypic Variance Due to Parent-of-Origin Effects Using Genomic Relatedness Matrices. [PDF]
We propose a new method, G-REMLadp, to estimate the phenotypic variance explained by parent-of-origin effects (POEs) across the genome. Our method uses restricted maximum likelihood analysis of genome-wide genetic relatedness matrices based on ...

Genetic variants influencing phenotypic variance heterogeneity [PDF]
Most genetic studies identify genetic variants associated with disease risk or with the mean value of a quantitative trait. More rarely, genetic variants associated with variance heterogeneity are considered. In this study, we have identified such variance single-nucleotide polymorphisms (vSNPs) and examined if these represent biological gene × gene or

Prediction of breeding values and selection responses with genetic heterogeneity of environmental variance [PDF]
There is empirical evidence that genotypes differ not only in mean, but also in environmental variance of the traits they affect. Genetic heterogeneity of environmental variance may indicate genetic differences in environmental sensitivity.

Variance Component Methods for Analysis of Complex Phenotypes [PDF]
INTRODUCTIONVariance component methods have a long history in human quantitative genetics as well as in agricultural genetics and animal breeding. They are designed for genetic analysis of continuously varying quantitative traits such as body mass index (BMI), cholesterol levels, or intelligence quotient.

Inheritance beyond plain heritability: variance-controlling genes in Arabidopsis thaliana. [PDF]
The phenotypic effect of a gene is normally described by the mean-difference between alternative genotypes. A gene may, however, also influence the phenotype by causing a difference in variance between genotypes.

THE CONTRIBUTION OF SOCIAL GROUP EFFECT TO VARIATION IN BOARS GROWTH [PDF]
The aim of the study was to estimate the contribution of group to phenotypic variance of daily gain on different intervals. The focus was on data structure and differences of variance components estimated with and without effect of the social group ...

Effects of interspecific gene flow on the phenotypic variance–covariance matrix in Lake Victoria Cichlids [PDF]
Quantitative genetics theory predicts adaptive evolution to be constrained along evolutionary lines of least resistance. In theory, hybridization and subsequent interspecific gene flow may, however, rapidly change the evolutionary constraints of a ...

Genetic Analysis and Molecular Breeding Applications of Malting Quality QTLs in Barley
Malting quality is an important determinant of the value of barley grain used in malting and brewing. With recent sequencing and assembling of the barley genome, an increasing number of quantitative trait loci (QTLs) and genes related to malting quality ...

Genetic analysis of environmental variation [PDF]
Environmental variation (V-E) in a quantitative trait - variation in phenotype that cannot be explained by genetic variation or identifiable genetic differences - can be regarded as being under some degree of genetic control. Such variation may be either
