  1. QTL name, cytological position with peak and 2 LOD interval, sex affected and estimates of additive (a) and dominance (d) effects on life span (in days), dominance ratio (d/a) and proportion of phenotypic variance VP explained by the QTL.
  2. Negative values of a indicate the LI4 line has the increasing allele at this QTL. This was accounted for in the calculation of the dominance ratio. Significant QTL effects (at P < 0.05) are shown in boldface. All QTL shown are supported both by composite interval mapping and single marker analysis.
