You can also breed parti carrier to parti carrier and get parti colored pups, that's how all of our parti lines today have initially popped up (a big surprise to the breeder).

Parti bred to Parti = 100% parti
Parti bred to carrier = 50% parti/50% carrier
Parti bred to traditional = 100% carriers
Carrier bred to carrier = 25% traditional, 25% parti, 50% carrier

Attached is an example of a carrier to parti cross born 12 days ago. I have 2 parti pups and 2 carrier pups
(50/50 split). Of course that's just the average, I've seen parti to carrier crosses that produced 3 parti and 1 carrier and others that produced all carriers (only 2 pups in the litter).
