The contribution of diet and genotype to iron status in women:a classical twin study [PDF]
, 2013 This is the first published report examining the combined effect of diet and genotype on body iron content using a classical twin study design. The aim of this study was to determine the relative contribution of genetic and environmental factors in ...

Epistasis Is a Major Determinant of the Additive Genetic Variance in Mimulus guttatus. [PDF]
PLoS Genetics, 2015 The influence of genetic interactions (epistasis) on the genetic variance of quantitative traits is a major unresolved problem relevant to medical, agricultural, and evolutionary genetics.

Animals, 2023 Monitoring the genetic variance of traits is a key priority to ensure the sustainability of breeding programmes in populations under directional selection, since directional selection can decrease genetic variation over time.

Genetic profile of total body energy content of Holstein cows in the first three lactations [PDF]
, 2005 Weekly total body energy content (TBEC) was calculated for 444 Holstein cows in their first 3 lactations. These calculations were based on body lipid and protein changes predicted from weekly changes in body condition score and live weight of each cow ...

Genetic imprinting analysis for alcoholism genes using variance components approach [PDF]
BMC Genetics, 2005 Abstract Genomic imprinting, which is also known as the parent-of-origin effect, is a mechanism that only expresses one copy of a gene pair depending upon the parental origin. Although many chromosomal regions in the human genome are likely to be imprinted, imprinting is not accounted for in the usual linkage analysis.

Semiparametric variance components models for genetic studies with longitudinal phenotypes [PDF]
Biostatistics, 2012 In a family-based genetic study such as the Framingham Heart Study (FHS), longitudinal trait measurements are recorded on subjects collected from families. Observations on subjects from the same family are correlated due to shared genetic composition or environmental factors such as diet.
