What would you get if you bred a Killerbee to a Queen bee?
All a Killer Bee would do is give every offspring the pastel gene. All the pastel babies could also carry the spider or lesser gene. So you could Killer Bees, Bees, Lessers, Queen bees, Super Pastels, Pastels, and a Super Queen Bee (not sure if you would call it that.). With both parnets carring the Spider and Pastel gene you would have a better chance of getting the Spider gene and a chance of a Super Pastel. There would be no normals.
