  • a When the QTL is significant in only one backcross, the position and support interval are given for that QTL. When both backcrosses have significant QTL, the position and support interval are presented for the QTL with the highest LOD score.

  • b The estimated positions and effects for model II can be influenced by linked QTL, if present.

  • c Defined as that effect caused by the replacement of a simulans allele by a sechellia allele. Given as a percentage of the species difference for X-linked QTL and as a percentage of half the species difference for autosomal QTL.

  • d Support interval is a 95% confidence interval based on 200 bootstraps of the original data. All other intervals are two-LOD drop-offs from the QTL peak. See text for details.

  • e LOD score was not significant.
