eQTL mapping of the Ttf2 gene on chromosome 3 using results from EMMA and MENDEL. Six founder strains were used: C57Bl6, DBA2, A, AKR, ILn, and RIII. The solid curve displays the –log10(P-values) from MENDEL’s association test. EMMA’s results are displayed as asterisks. The physical location of the Ttf2 gene is shown by the small solid rectangle near the x-axis directly under the dominant peak. The tick marks at the top of the graph are the locations of the SNPs used by EMMA.
