## Description

Approximate positions of quantitative trait loci (QTL) based on data released by the Jackson Lab Mouse Genome Informatics database (MGI) on 8 Nov. 2004.

## Method

Most of the QTL records contain an STS marker that exhibits the peak logarithm-of-odds (LOD) score for the marker-phenotype association. This peak marker is represented by a thick (tall) bar. For records that have two flanking STS markers (with or without peak LOD score data), the QTL region is represented by a thinner bar spanning the interval between the two markers. Where both flanking markers and peak LOD score are available, the thick bar is superimposed upon the thinner bar.
