... theory states that inheritance patterns may be generally explained by assuming that genes are located in specific sites on chromosomes (recall that each gene makes a specific protein). Sutton was the first to point out that chromosomes obey Mendel's rules—the first clear argument for the chromosome ...

This study nicely illustrates the use of molecular markers to identify bacterial associations that confer phenot ...

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.
