They really won’t look similar to a super blk pastel or 8 ball. They’ll still have varying amounts of pattern. You can see by looking up huffman combos on the market.
I haven’t worked with Huffman personally, so I don’t know how much influence it would have in combos. Enchi is also in the same complex and I personally have yet to see a cinny or blk pastel enchi with a heavy nasal defect like the duckbilling. So maybe huffman is the same in that aspect.
Kinking and Duckbilling is the issue with blk pastel and cinny. It’s mostly in the supers or allelic combo of the two. I have seen one or two single genes with a split lip, but that could also be an incubation issue not the actual genetic defect.
There’s varying degrees of it from just the snout having that more ducklike ‘bill’ look to things like split palate and spilt lips. I’ve personally seen fairly ‘normal’ looking super cinnys have a more upward flicking tongue motion than other morphs as well. Sometimes reaching back almost to touch the snout.
There’s a good post about Huffman here:
