QTL (Quantitative Trait Loci)

Quantitative Trait Loci (QTL) are specific regions in an organism's DNA that influence measurable traits, such as height, crop yield, or milk production. These traits vary continuously and are affected by multiple genes and environmental factors. By identifying QTL, scientists can better understand how genetic variations contribute to these traits, aiding in selective breeding or genetic research. Essentially, QTL are markers that link parts of the genome to specific characteristics, helping us understand the genetic basis of complex traits that don't follow simple patterns.
