Fig. 2From: Genetic analysis of variation in lifespan using a multiparental advanced intercross Drosophila mapping populationGenome scan for lifespan QTL. The black solid line indicates the LOD score following a scan for QTL contributing to variation in lifespan in the DSPR. The x-axis indicates genetic distance, and genetic positions 54 and 47 are the sites of the centromeres on chromosomes 2 and 3, respectively. The red line is a permutation-based genomewide 5 % threshold (LOD = 7.08). Five QTL show peaks with LOD scores higher than this threshold, their positions are indicated with asterisks, and the codes Q1-Q5 used throughout the text are provided above the plot. We also provide genomewide 10 % (gray dashed line, LOD = 6.64) and 20 % (gray dotted line, LOD = 6.24) thresholds. Peaks surviving these more liberal thresholds (at 57cM and 70cM on 2R, and 70cM and 103cM on 3R) are less compelling candidates to contribute to lifespan variationBack to article page
