... New Alleles • For a given gene, many alleles, or variations, may exist. Any new allele must begin as a mutation of an existing allele. • Most new alleles are simply the result of silent mutations, so these changes make little difference to the organisms in which they occur. • However, sometimes a ne ...

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.
