I'm not going to go into a long discussion on genetics, but I will try to sum it up a little bit.
MM=double merle
Mm=regular merle dog
mm=solid color, no merle
Each parent gives up half of this trait, so if you breed two merle dogs (Mm) to each other, the probability of having MM dogs is 25%, regular merle (Mm) dogs is 50%, and solid color (mm) is 25%. Now if you breed a merle dog (Mm) to a solid colored (mm), you have a 25% chance of having merle dogs (Mm) and a 75% chance of having solid colored (mm) dogs. Breeders do this because people think the look of a merle colored dogs is cool, and this is the best chance of having higher numbers of merle puppies, even though the probability of having physical defects is 25%.
Now there is a chance, you can get a litter of 100% double merle puppies that will most likely have physical defects, and there is also a chance that you won't have any MM dogs in the litter. There is also a chance that a dog can be MM and never show any traits of being MM, which can really mess with a good breeding program.
Genetics is all about chance and probability, which is always a flip of a coin. The one thing a breeder can do is breed responsibly to help your chances of getting what you want. If you want healthy leopards that will actually hunt for you, then breed a merle to a solid color, and only breed leopards that actually hunt. You will help yourself out in the long run.
NOTE: This is just my opinion and heaven forbid that it is different from anyone else's. So don't get butt-hurt if it isn't exactly the same as yours or someone else's.
