Quantitative trait locus (QTL) mapping is an analysis of the number, genomic locations, effects, and interactions of quantitative trait loci (QTL). When examining a set of quantitative traits, QTL mapping looks at the link between genotype at various genomic regions and phenotype. Finding the chromosomal regions that significantly affect how quantitative traits differ among populations is the primary objective of QTL mapping. This localization is crucial for both the eventual identification of the implicated genes and our comprehension of the genetic mechanisms behind the variance.
