Linkage evidence on bovine chromosome 5 for the locus affecting the eumelanin and phaeomelanin dilution in Charolais crosses. F-ratio profile obtained for the dilution-related traits Quantitative-dilution, Quantitative-Black and Quantitative-Red on chromosome 5. Dashed lines indicate information content (right y-axis). Marker positions are identified as triangles above the x-axis. The peak of the statistical profiles was flanked in all the cases by markers ETH10 and DIK5248. The bootstrap 95% CI for Quantitative-Black is indicated as a grey box above the x- axis. The position of the SILV gene according to our linkage analysis is represented on the x-axis.
