Biewers/Parti's get a "spotting gene" from both parents.. they may get an Irish spotting from one and a Piebald from another.. I believe, the Irish spotting is dominant.. I can't remember exactly, I'd have to go look that up.. of course, the parent also got two genes from their parent.. so you need to take that into consideration also.. the spotting gene is actually just a pattern of how much white there is or actually, how much color there isn't.. white is lack of color.. ranging from no white to extreme piebald.. (all white).
A litter of Biewers or a litter of Partis may have some pups that have the Irish spotting pattern and some that have the piebald pattern and some that have the extreme piebald.. all in the same litter.. it depends on the roll of the dice on what genes the parents gave to each pup.. there are also modifiers for face color placement that may also come into play.. it gets very exciting!!
Just because dogs have different spotting patterns, does not mean genetically they are different dogs.. they just have different spotting patterns controlling the patterning of their spots...or, it even could be the same spotting pattern with different degrees of color.
Clear as mud right???
