QTL or Quantitative Trait locus are chromosome sequences in which multiple genes contribute to a quantitative trait.
QLT is a locus that correlates with variation of quantitative trait in the phenotype of the population of an organism. It is an statistical method that links two type of information phenotypic and genotypic data in an attempt to explain the genetic variation in complex trait.
