Quantitative trait locus for starvation resistance in an intercontinental set of mapping populations of Drosophila melanogaster

Starvation resistance (SR) is an important trait for survival of insects in the wild. We used recombinant inbred lines (RIL) to search for quantitative trait loci (QTL) in crosses between intercontinental inbred lines that were originally selected for heat-knockdown resistance. SR was measured as th...
