In addition, this gene results in heterochromia iridis, a disorder in which one eye is larger than the other. 

If two Merles are let to mate, they may result in a dog with two copies of the MM gene, known as a “Double Merle.” The base color dominates this dog with relatively little melanin and only a few patches of various colors.

The Frenchie’s base coat’s lighting creates a Merle pattern. As a result, the black patches continue to exist, giving the puppies the Merle trait. 

The most prevalent markings on their fur are dark brown or black, and the dominant color is typically a mixture of white, cream, or fawn with dark colors. Their fur can have hundreds of different markings. The Merle must be mated with a French Bulldog and a Frenchie that has already undergone Chihuahua-Chihuahua crossbreeding to achieve its stunning hues.
