Don't want to start up a new thread and this Q is still about Yellow Bellied....

A friend of mine got male Bumblebee he wants to breed next year. He's still can't decide between breeding his bee with which morph.

What will you get if you breed bumblebee with Yellow Bellied? Please tell the % of each morph that will come from bee x YB.

What's the % of killer bee when you breed Bumble bee with Pastel. My guess is 25% correct?

If I breed Pastel YB with Pastel, will I have a chance to get Super Pastel YB? Is this morph exist? How does this morph look?

Thanks
T
