Sequential Quantitative Trait Locus Mapping in Experimental Crosses

open access: yesStatistical Applications in Genetics and Molecular Biology, 2007
The etiology of complex diseases is heterogeneous. The presence of risk alleles in one or more genetic loci affects the function of a variety of intermediate biological pathways, resulting in the overt expression of disease. Hence, there is an increasing focus on identifying the genetic basis of disease by systematically studying phenotypic traits ...

Novel Resampling Improves Statistical Power for Multiple-Trait QTL Mapping

open access: yesG3: Genes, Genomes, Genetics, 2017
Multiple-trait analysis typically employs models that associate a quantitative trait locus (QTL) with all of the traits. As a result, statistical power for QTL detection may not be optimal if the QTL contributes to the phenotypic variation in only a ...

Quantitative trait locus analysis of agronomic and quality-related traits in cultivated peanut (Arachis hypogaea L.)

open access: yesTheoretical and Applied Genetics, 2015
Key messageSSR-based QTL mapping provides useful information for map-based cloning of major QTLs and can be used to improve the agronomic and quality traits in cultivated peanut by marker-assisted selection.AbstractCultivated peanut (Arachis hypogaea L.)

Gene by environment QTL mapping through multiple trait analyses in blood pressure salt-sensitivity: identification of a novel QTL in rat chromosome 5

open access: yesBMC Medical Genetics, 2006
Background The genetic mechanisms underlying interindividual blood pressure variation reflect the complex interplay of both genetic and environmental variables.

Detection and Mapping of Quantitative Trait Loci that Determine Responsiveness [PDF]

open access: yes, 2004
Exposure to 70% N2O evokes a robust antinociceptive effect in C57BL/6 (B6) but not in DBA/2 (D2) inbred mice. This study was conducted to identify quantitative trait loci (QTL) in the mouse genome that might determine responsiveness to N2O.

The Population Genetic Signature of Polygenic Local Adaptation

open access: yes, 2014
Adaptation in response to selection on polygenic phenotypes may occur via subtle allele frequencies shifts at many loci. Current population genomic techniques are not well posed to identify such signals.

A Novel Root-Knot Nematode Resistance QTL on Chromosome Vu01 in Cowpea. [PDF]

open access: yes, 2019
The root-knot nematode (RKN) species Meloidogyne incognita and M. javanica cause substantial root system damage and suppress yield of susceptible cowpea cultivars.

Quantitative trait locus mapping of deep rooting by linkage and association analysis in rice

open access: yesJournal of Experimental Botany, 2015
Highlight Major quantitative trait loci (QTLs) of rice deep rooting were identified by combined linkage-based and linage disequilibrium-based QTL mapping in this study.

Evolution of assortative mating in a population expressing dominance.

open access: yesPLoS ONE, 2011
In this article, we study the influence of dominance on the evolution of assortative mating. We perform a population-genetic analysis of a two-locus two-allele model.

A new method for Quantitative Trait Loci Detection [PDF]

open access: yes, 2010
We consider the likelihood ratio test (LRT) process related to the test of the absence of QTL on the interval $[0,T]$ representing a chromosome (a QTL denotes a quantitative trait locus, i.e. a gene with quantitative effect on a trait).
