Development of multiple interval mapping for mapping QTL in

... Genes determining a quantitative trait or regions on chromosomes underlying a quantitative trait (Geldermann, 1975) are called quantitative trait loci or QTL. Unlike the gene determining a Mendelian trait, an individual QTL usually has a small effect on a quantitative trait. The total effect (which ...

... Next, quantitative genetic theory makes the assumption that the mean of A among parents is equal to that in offspring: e.g., E(A, t + 1) = ER (A, t). In 2-sex models this requires that the expected value of A in an offspring is the mid-point of the breeding value of its parents. Given this assumptio ...

Quantitative trait locus

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.Quantitative traits are phenotypes (characteristics) that vary in degree and can be attributed to polygenic effects, i.e., the product of two or more genes, and their environment.
