Definition

A quantitative trait locus (QTL) is a polymorphic locus which contains alleles that differentially affect the expression of a continuously distributed phenotypic trait. Usually it is a marker described by statistical association to quantitative variation in the particular phenotypic trait that is thought to be controlled by the cumulative action of alleles at multiple loci. http://rgd.mcw.edu/tu/qtls/
