QTL: What are Quantitative Trait Loci and their Importance in Genetics?

QTL stands for Quantitative Trait Loci. It refers to specific regions of a chromosome that are associated with the variation of a quantitative trait, such as height, weight, or blood pressure, in a population. QTL analysis is a method used in genetics to identify these regions and understand the genetic basis of complex traits. By identifying QTLs, researchers can gain insights into the genes and genetic factors that contribute to the variation of a trait and potentially develop strategies for selective breeding or targeted therapeutic interventions.
