The closest example of this in BPs would be the BluEL complex or YB/Whirwind or Cinny/Black Pastel. In each of these the mutants are inc-dom to WT but allelic to the others within the group (i.e. Butter is allelic to Lesser is allelic to Mojave is allelic to Phantom is allelic to Russo.)



Wild type is neither recessive nor dominant nor co-dom. It is just a baseline by which mutations are measured against.
Hmmm. That is different than what I was taught in college. At least it is different than how I remember it; it was quite a few years ago.

Do you happen to have any sources where I could study it and make sure I understand it properly?
