It is way confusing

Spector/Whirlwind/het superstripe is all the same thing. The other 1/2 of the puzzle to make a superstripe.

Superstripe is a spector and yellowbelly. The superstripe breedings so far have shown that the superstripe is a super form of two different morphs that reside on the same allele (just like a mojave/lesser leucy) because all of the offspring was either spector or yellowbelly from superstripe to normal breedings.

SO....if that's true then a Superstripe bred to a Superstripe would produce:
1/4 Ivories
1/2 Superstripes
1/4 Super Spectors (which I believe hasn't been done)

Coolest breeding IMO would be Ivory to Super spector.....all superstripes!

Hope that helps
