If the goal is to weed out the inc-doms that is a bit easier.
Dominant ball morphs:
Calico/Sugar -- Suspected. No visual super produced to date but may have lethal homozygous, data is too spotty to confirm/deny
Congo -- Per Vin Russo
Pinstripe -- Has always been labeled as dominant but there are a couple of breedings that indicate that may not be correct
Leopard -- Suspected but one breeder thinks it may be otherwise
