Oligo(dT) lengths of 81–86 bp are observed in standard and harlequin merle dogs. Photographs and chromatograms from fragment analysis data are shown for a harlequin (a) and a standard merle (b). Amplicon size in base pairs is shown on the x-axis, and the y-axis measures signal intensity (RFU). Genotypes are given for each dog above their chromatogram with M denoting their inherited Merle allele, and m representing their non-pictured, wild-type allele
