H Locus
From $49.00
Merle-colored Great Danes have dark spots on a diluted/grey background. The Harlequin gene causes a white background and the spots increase in size. Dogs that are not merle, cannot express the Harlequin color/pattern. Breeding two dogs that both have a copy of the H locus “NH” is not recommended. A dog with two copies of Harlequin has not been observed and is presumed to be lethal in utero. This gene is inherited as a dominant trait.
Test Results:
Possible Genotypes:
NN– 2 copies of the non-harlequin allele
NH–1 copy of the non-harlequin allele & 1 copy of the harlequin allele, harlequin is expressed if merle gene is also present
HH– 2 copies of the harlequin allele, lethal in utero
DNA marker tested – PSMB7 :c.146T>G
