Figure 5From: Quantitative trait locus mapping of genes that control body length and plasma insulin-like growth factor 1 level in miceInteraction LOD score plots for the IGF1 levels. A horizontal dashed line indicates significant threshold LOD scores determined by 1,000 permutations. Solid lines denote the LOD scores when the agouti genotypes (non-Ay or Ay) were included as covariates. Horizontal dashed lines indicate significant threshold LOD scores determined by 1,000 permutations.Back to article page
