A quantitative trait locus (QTL) is a section of DNA (the locus) that correlates with variation in a phenotype (the quantitative trait).The QTL typically is linked to, or contains, the genes that control that phenotype.QTLs are mapped by identifying which molecular markers (such as SNPs or AFLPs) correlate with an observed trait. This is often an early step in identifying and sequencing the actual genes that cause the trait variation.he QTL typically is linked to, or contains, the genes that control that phenotype.
