The evolution of genetic architectures underlying quantitative traits [PDF]
Proc. R. Soc. B 280:1769, 2012 In the classic view introduced by R. A. Fisher, a quantitative trait is encoded by many loci with small, additive effects. Recent advances in QTL mapping have begun to elucidate the genetic architectures underlying vast numbers of phenotypes across diverse taxa, producing observations that sometimes contrast with Fisher's blueprint.

A High-Density Genetic Linkage Map and QTL Mapping for Sex in Black Tiger Shrimp (Penaeus monodon)
Frontiers in Genetics, 2019 The black tiger shrimp, Penaeus monodon, is important in both fishery and aquaculture and is the second-most widely cultured shrimp species in the world.

The bovine QTL viewer: a web accessible database of bovine Quantitative Trait Loci
BMC Bioinformatics, 2006 Background Many important agricultural traits such as weight gain, milk fat content and intramuscular fat (marbling) in cattle are quantitative traits.

A comparison of the Benjamini-Hochberg procedure with some Bayesian rules for multiple testing [PDF]
IMS Collections 2008, Vol. 1, 211-230, 2008 In the spirit of modeling inference for microarrays as multiple testing for sparse mixtures, we present a similar approach to a simplified version of quantitative trait loci (QTL) mapping. Unlike in case of microarrays, where the number of tests usually reaches tens of thousands, the number of tests performed in scans for QTL usually does not exceed ...

High Dimensional Gaussian Graphical Regression Models with Covariates [PDF]
arXiv, 2020 Though Gaussian graphical models have been widely used in many scientific fields, relatively limited progress has been made to link graph structures to external covariates. We propose a Gaussian graphical regression model, which regresses both the mean and the precision matrix of a Gaussian graphical model on covariates. In the context of co-expression

Role of genetic polymorphisms in transgenerational inheritance in budding yeast [PDF]
Genomics, 106: 23-29 (2015), 2013 Transgenerational inheritance of a trait is presumably affected by both genetic and environmental factors but remains poorly understood. We studied the effect of genetic polymorphisms on transgenerational inheritance of yeast segregants that were derived from a cross between a laboratory strain and a wild strain of Saccharomyces cerevisiae.

Genetics and Molecular Biology, 2012 Spawning time in salmonids is a sex-limited quantitative trait that can be modified by selection. In rainbow trout (Oncorhynchus mykiss), various quantitative trait loci (QTL) that affect the expression of this trait have been discovered.

Multiallelic models for QTL mapping in diverse polyploid populations
BMC Bioinformatics, 2022 Quantitative trait locus (QTL) analysis allows to identify regions responsible for a trait and to associate alleles with their effect on phenotypes. When using biallelic markers to find these QTL regions, two alleles per QTL are modelled. This assumption

G3: Genes, Genomes, Genetics, 2019 Bermudagrass (Cynodon (L.)) is the most important warm-season grass grown for forage or turf. It shows extensive variation in morphological characteristics and growth attributes, but the genetic basis of this variation is little understood. Detection and

Accurate Estimation of Quantitative Trait Locus Effects with Epistatic by Improved Variational Linear Regression [PDF]
arXiv, 2015 Bayesian approaches to variable selection have been widely used for quantitative trait locus (QTL) mapping. The Markov chain Monte Carlo (MCMC) algorithms for that aim are often difficult to be implemented for high-dimensional variable selection problems, such as the ones arising in epistatic analysis.
