LOL.
For hobby breeders it makes sense (to a degree) lol.
Bumblebees being double gene morphs will make the following when bred to a normal.
25% Bumblebees,
25% Spiders,
25% Pastels,
25% Normals.
75% chance of getting a morph.
Most small breeders start out with normal females and build their collection that way. I got a buddy who owns a successful breeding company (I wont say which one) But he still has five normal females that he breeds in with his males every year.
