Yes, fewspots ALWAYS produce appaloosa, because they're homozygous for appaloosa. It's so hard to get a novice to understand that the fewspots (many with only spots on their skin that you never see -- so they really look "unspotted" are an Appaloosa breeder's dream!
So many people want the leopards, but they only throw the gene 50% of the time, so you can breed 2 full leopards together and 25% of the time get NO spots. Happened to me once, and I just couldn't believe it, and at the time I had probably 5 leopards here. Dumped all but Spotty -- who seemed to throw his appy gene every time when bred appy, and traded them in for fewspots and snowcaps -- who are also homozygous.
I just LOVE the appaloosa genetics. Then you have the PATN1 genes....so much fun!!
