Educational Software for Mapping Quantitative Trait Loci (QTL)
Journal of Natural Resources and Life Sciences Education, 2007This educational software was developed to aid teachers and students in their understanding of how the process of identifying the most likely quantitative trait loci (QTL) position is determined between two flanking DNA markers. The objective of the software that we developed was to: (1) show how a QTL is mapped to a position on a chromosome using a ...

Quantitative trait loci: Mapping the future of QTL's
Heredity, 2005A recent paper published in Nature represents a first in the attempt to map and sequence a true quantitative trait loci (QTL) – a gene with a small effect and complex expression. This study highlights both the promise and hazards of the road ahead as we seek to diagnose all the genes contributing to complex phenotypes.

Investigating temperament traits in cattle for quantitative trait loci (QTL) identification
Proceedings of the British Society of Animal Science, 2002Farm animals show individual variation in their behavioural responses to handling and management systems on farms. These behavioural responses are presumed to reflect underlying temperament traits such as fear or aggression. Information about the location of genes that influence temperament traits could be used in selective breeding programmes to ...

Identification of Quantitative Trait Loci (QTLs) in Aquaculture Species
Reviews in Fisheries Science & Aquaculture, 2014The production of capture fisheries is decreasing and genetic resources are reducing in aquaculture species due to overexploitation of natural resources. Marker-assisted selection (MAS) is one of the ways to rapidly increase genetic gain for enhancing fish production, by improving important traits.

Identification of Quantitative Trait Loci (QTLs) for Fruit Quality Traits in Apple
Plant Molecular Biology Reporter, 2013A segregating mapping population of “Co-op 17” × “Co-op 16” was used to identify quantitative trait loci (QTLs) associated with various fruit quality traits in apple. Phenotypic data were collected over 2 years for fruit circumference (in centimeter), diameter at midpoint (in centimeter), length (in centimeter), weight (in gram), total soluble solids ...

IQI: Individualized Quantitative trait loci (QTL) Index
AbstractThere is currently no standard efficient method to precisely detecting and characterizing the difference of quantitative trait loci (QTL) effect among groups and/or populations at individual level. The main reason is that the traditional global regression based QTL analyses can only derive an overall effect of genetic variants on the ...Jing Xu +18 more

Quantitative trait loci (QTL) for reducing aflatoxin accumulation in corn
Molecular Breeding, 2016Aflatoxin produced by Aspergillus flavus in corn poses significant health risks to both humans and livestock. Exploitation of host-plant resistance in breeding programs is a sustainable way to minimize aflatoxin contamination. Identification of quantitative trait loci (QTL) associated with resistance to aflatoxin accumulation in kernels can accelerate ...

Provisional Quantitative Trait Loci (QTL) for the Aschoff Effect in RI Mice
Physiology & Behavior, 1998Mice of the CXB recombinant inbred (RI) panel were phenotyped for period of locomotor activity in continuous dark (tau) and in continuous 10-lux light (tauLL). There were significant differences in the effect of light on period, delta tau (tauLL-tau), among CXB RI strains and their progenitors.

Quantitative trait loci (QTL) for circadian rhythms of locomotor activity in mice
Behavior Genetics, 1995The locomotor activity of male mice (Mus musculus) was monitored by infrared photo-electric beams under three lighting regimens: LD (12 h of light and 12 h of dark), DD (constant dark), and LL (constant broad-spectrum light, 10 lux). Circadian period of locomotor activity (tau) was compared among 3 inbred strains of mice, C57BL/6J (B6), BALB/c (C), and
