Pretty much, kinda.
Without using a "super" (homozygous co-dom animal), you still have that 1/8 or 1/16 or even 1/128 chance, per egg, that you might get a normal. You won't necessarily get 1/8 normals.
If you're pairing morphs with 3+ genes, the likelihood that you will get a normal significantly decreases ... Though of course, you could still have miserable luck and hit on that 1/128 chance with your $15,000 breeding.
You also have to consider what else you could potentially produce. If you bred your male bee to a super lesser BEL, probably the "best" (highest-gene animal, if that's what you're going for) you could produce would be a lesser pastel spider. If, however, you bred him to a female pastel lesser (which is actually a less expensive animal), the "best" you could produce would be a super pastel lesser spider. However, you also may get normals with that breeding.
