We proposed a faster pedigree-based generalized multifactor dimensionality reduction algorithm, called PedG-MDR II (PII), to detect gene-gene interactions underlying complex traits. Inherited from our previous framework of PedGMDR (PI), PII can handle both dichotomous and continuous traits in pedigree-based designs and allows for covariate adjustment. Compared with PI, this faster version can t...

in order to correlation diversity assessment among the quantitative and fiber quality traits, five cultivars of tetraploid cotton (g. hirsutum) cultivars were evaluated at varamin region in 2009. in this study the populations of the cultivar lines were planted near together and 100 lines randomly were selected at the end of the season followed by measuring seed cotton yield and quantitative and...

Low back (LBP) and chronic widespread musculoskeletal pain (CWP) both have a significant genetic component and are associated with increased body mass index (BMI). We examined whether LBP and CWP share common genetic factors, and to what extent this correlation is modified by the genetic factors influencing BMI. Genetic analysis of binary traits such as pain is not simple, particularly if their...

knowledge about genetic diversity is an essential step towards conservation of genetic resources and developing further strategies for plant improvement. the objective of this research was to evaluate the agronomical and morphological traits and determine the level of variation within wild barley ecotypes especially for acclimation traits. in this study 188 ecotypes of wild barley (hordeumspont...

Human genome resequencing technologies are becoming ever more affordable and provide a valuable source of data about rare genetic variants in the human genome. Such rare variation may play an important role in explaining the missing heritability of complex human traits. We implement an existing method for analyzing rare variants by testing for association with the mutational load across genes. ...

The threshold expression of dichotomous phenotypes that are environmentally cued or induced comprise the vast majority of phenotypic dimorphisms in colour, morphology, behaviour and life history. Modelled as conditional strategies under the framework of evolutionary game theory, the quantitative genetic basis of these traits is a challenge to estimate. The challenge exists firstly because the p...
