Quantitative Trait Locus
(QTL) detection
Many economically important traits show quantitative inheritance:
segregating progeny show a continuous pattern of expression rather
than the discrete classes characteristic of Mendelian, or qualitative,
inheritance. The loci that are determinants of quantitative trait expression
are termed Quantitative Trait Loci (QTL). QTL are identified via statistical
procedures that integrate genotype (i.e. molecular marker) and phenotype
data. QTL are assigned chromosome locations based on the positions
of markers on linkage maps. This figure outlines the QTL detection
process. Text Version of information.
