The goal of quantitative trait loci (QTL) mapping is to identify genes underlying an observed trait in the genome using genetic markers. In experimental organisms, the QTL mapping experiment usually involves crossing two inbred lines with substantial differences in a trait, and then scoring the trait in the segregating progeny. A series of markers along the genome is genotyped in the segregating progeny, and associations between the trait and the QTL can be evaluated using the marker information. Of primary interest are the positions and effect sizes of QTL genes.
