Quantitative trait loci (QTL) mapping is a genome-wide inference of the relationship between genotype at various genomic locations and phenotype for a set of quantitative traits in terms of the number, genomic positions, effects and interaction of QTLs.

Keywords: quantitative tracts; quantitative trait loci; QTL mapping; linkage analysis; genetic architecture of complex trait

Figure 1. Genetic mapping of QTL on wing shape from a long-term divergent selection in chromosomes 3 and 2 of Drosophila melanogaster. Lod score curves of a multiple interval mapping analysis are shown on a linkage map of chromosomes 3 and 2 (a, b). Marker positions are denoted by triangles. See also
