1. A chromosomal region or segment that contains one or more genes controlling a quantitative (continuous) trait, identified through genetic mapping and statistical analysis
The researchers identified a QTL on chromosome 3 that controls grain yield in wheat.
Os pesquisadores identificaram um QTL no cromossomo 3 que controla a produtividade de grãos no trigo.
2. A genomic location associated with variation in a complex trait that shows continuous phenotypic distribution rather than discrete categories
Multiple QTLs contribute to human height, each with small additive effects.
Múltiplos QTLs contribuem para a altura humana, cada um com pequenos efeitos aditivos.
QTL is a specialized term primarily used in genetics, plant breeding, and quantitative biology research. It is fundamental to modern genomics and agricultural improvement programs in both Brazil and Portugal. The term is typically not translated in scientific publications, as 'QTL' serves as the universal abbreviation in the scientific community. Brazilian agricultural research, particularly in crops like sugarcane, corn, and soybeans, frequently employs QTL analysis. In the USA, QTL studies are central to crop improvement and understanding complex disease genetics.
