A modest decrease in the recombination between a pair of loci (rij ⬍ 1/3 for the plant model, rij ⬍ 1/6 for the animal model when pi = p j = 1/2 and bi = b j ) suffices to reverse that trend, however, so that stronger assortment actually decreases the ove ...

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.
