Understanding Cryptic vs Classic Merle Dogs

How do cryptic merles differ from classic merle dogs? The difference between cryptic merles and classic merle dogs lies in the length of the genetic insertion within the SILV pigment gene and how that length affects the dog's physical appearance....

Discover the key differences between cryptic and classic merle dogs, from genetic factors to physical appearance. Uncover the merle mystery!

Understanding the Lethal Harlequin Gene in Dogs

What is the lethal effect of the Harlequin gene? The Harlequin gene is embryonic-lethal when a dog inherits two copies of it. If a puppy inherits this homozygous HH genotype, the mutation causes embryonic death very early during pregnancy, meaning the embryo fails to form entirely and is instead reabsorbed into the womb. Because this early embryonic failure does not result in observable stillbirths, a dog with two copies of the Harlequin gene has never been observed or tested....

Discover the lethal effects of the Harlequin gene in dogs and why it prevents true breeding in Great Danes. Learn more about this mutation.
