STATISTICALLY what you could get by breeding dapples and double dapples.

M = dapple gene (This is a dominant gene and only one is needed to be a dapple and would be Mm genetically ) m = non dapple gene (This is a recessive gene and any non dappled dog will be mm genetically.)

If two non dappled dogs (mm X mm) are bred together then NO pup in that litter would be dapple. 0%

If a dapple dog (Mm) is bred to a non dappled dog (mm) then STATISTICALLY you should get 50% of the litter as dapples (Mm) and 50% as non dapples (mm). However, you could have all dapples or no dapples at all. My sister had a non dappled dachshund that was bred to a dapple and all 7 of her puppies were dapples.

If a dapple dog is bred to another dapple dog (Mm X Mm) then STATISTICALLY you should get 25% double dapples (MM), 50% dapples (Mm) and 25% non dappled (mm) pups.

If a double dapple dog (MM) is bred to a non dapple dog (mm) then 100% of the litter will be dapple pups (Mm).

If a double dapple dog (MM) is bred to a dapple dog (Mm) then STATISTICALLY you should get 50% double dapples (MM) and 50% dapples (Mm).

If two double dapple dogs are bred (MM X MM) then 100% of the litter will be double dapple.

It is not recommended to breed dapple to dapple due to health issues and the risk of genetic defects.
