Is it possible for the original carrier of morph to be super co-dominant?

According to vin Russo the first congo was a super congo, however it is considered dominant, not co-dom

Cool! Thanks for the information!

A super congo (with a pair of congo mutant genes) has two congo parents, each with (most likely) a congo mutant gene paired with a normal gene. Neither congo parent looks normal. As far as I am concerned, that answers the OP's question with a yes.
