H-Lokus (Harlekin) Rassebestimmung b/b) or chocolate coat andHarlequin is a complex pigmentary trait of coat colour, characterized by a pattern of distinctive black patches on a white background. It is controlled by heterozygous mutations of merle locus and a modifier harlequin locus. The harlequin gene only influences the dogs phenotype in combination with the merle gene. If a dog has a non merle genotype (mm) the harlequin gene will not influence the dog's phenotype. Animals with HH genotype are not viable,
