Merle Coat Genetics

Dogs with one copy of the Merle gene (heterozygous) typically display the Merle coat pattern, while those with two copies (homozygous) may exhibit a “double Merle” coat that can come with increased health risks.

The Merle gene works by diluting the pigmentation of the base coat color, creating patches or streaks of lighter or darker colors throughout the fur. This effect is most pronounced in breeds like the American Bully and Tri -Colored Bully where the Merle pattern stands out prominently against the breed’s usual coat colors.

Difference Between a Single Merle and a Double Merle

The terms “single merle” and “double merle” refer to different genetic patterns found in certain dog breeds, particularly those with merle coat patterns. Here’s an explanation of each:

Single Merle (Mm)

      • A single merle dog has one copy of the merle gene (Mm) inherited from one parent.
      • The merle gene is responsible for diluting the base coat color and creating a mottled or patchy appearance in the coat, along with affecting eye color.
      • Single merle dogs typically have normal pigmentation in their eyes, such as brown, amber, blue, or a combination of colors.
      • Breeding two single merle dogs together can produce single merle, non-merle, or double merle puppies, depending on the genetic combinations.

Double Merle (MM or mm)

    • A double merle dog has inherited two copies of the merle gene (MM or mm), one from each parent.
    • This occurs when two merle dogs are bred together, resulting in a 25% chance of producing a double merle puppy in each litter.
    • Double merle dogs often have predominantly white coats with patches of merle coloring, along with higher chances of having visual and/or auditory impairments.
    • Common issues associated with double merle dogs include deafness, blindness, and other health problems related to improper pigment development in the eyes, ears, and skin.

It’s crucial for responsible breeders and owners to understand the genetics behind merle patterns to avoid unintentionally producing double merle puppies, which can face significant health challenges. Double merle dogs are often associated with increased risks of sensory disabilities and should be handled with special care and consideration for their unique needs.
