David, I am trying to get a handle on bp genetics, so I was wondering if you could give more detail on a bumblebee x super pastel cross.

I used a wizard and got 25% each: pastel, bumblebee, super pastel and killer bee. I have no idea how to attempt it manually with a Punnet square. I can do simple recessives and dominants that way, but get lost when the co-doms are added in.
