Figure 3From: A major QTL affects temperature sensitive adult lethality and inbreeding depression in life span in Drosophila melanogasterLOD scores for life span. Graphs depict LOD scores for the major chromosomes, when testing for QTL affecting female (A, B and C) and male (D and E) life span. For each sex, the two mapping populations are depicted. B i denotes the mapping populations derived from F2 males crossed to control females (i = 1) or lethal females (i = 2). If LOD scores exceed the significance threshold (horizontal line in figure), this indicates a QTL is segregating for life span at that position. QTL names correspond to those used in Table 2. The ticks indicate marker positions.Back to article page
