A recent paper published in Nature represents a first in the attempt to map and sequence a true quantitative trait loci (QTL) – a gene with a small effect and complex expression. This study highlights ...

What if you knew exactly how much good time you had left in your current chapter of life—and could design your days around that? That’s the premise of Quality Time Left (QTL), a shorthand for making ...

Multi-parental populations (MPPs) have been proposed as outstanding genetic resources for mapping QTL in crops. MPPs are based on the intercrossing of genetically divergent parental lines to produce a ...
