Quantitative trait locus (QTL)

Positional Cloning of the human quantitative trait locus underlying taste sensitivity to phenylthiocarbamide.

Subsequent comparative mapping of the trait locus with the gene-rich maps of the human and the mouse may reveal candidate genes for the trait in question.

A quantitative trait locus (QTL) is a region of DNA that is associated with a particular phenotypic trait.

A quantitative trait (see quantitative trait locus) is a measurable trait that shows continuous variation, such as height or weight.

A person's genotype for a multifactorial trait can interact with environment to produce varying phenotypes (see quantitative trait locus).

Quantitative trait locus which relates gene expression to genotypes.

Background Many authors [ 1 2 3 4 ] have compared the statistical power of different methods for quantitative trait locus (QTL) mapping.

In this marker experiment, an additive quantitative trait locus was found to explain almost a quarter of the total phenotypic variation in second year height growth.
