Yellow Jacket

[lord jackel]

From what i understand it is, Bill has some ch Black Bellies, maybe he can post some pics... Im not sure yet what other traits are important, but i will find out soon.
I have a female with a black Belly ill post pics of later , i dont know if she is a real "Black Belly" or not, but she is one of my Fav c.h.

Thanks Jon...so what is the story here?
Similar to a yellow belly they enhance another trait (like brightening up a pastel)?
What else do they do?
What is the expectation for the Super Black Belly (all white)?

Sorry for all the questions just curious about some of these "new" morphs.
