Depends on the morph.
I have a spider bp. That's a dominant morph. If I pair him with a normal, I would get a 50% chance of a spider and a 50% chance of a normal for every egg that is laid.
I also have an albino bp. That's a recessive morph. If I pair him with a normal, I will have all normals that have hidden albino gene (if you put these guys next to a plain normal, you won't be able to tell the difference).
But say I have a super pastel (which I don't). That's a super form of a co-dominant gene. If I pair him with a normal, I would get all regular pastels (not super - the supers are brighter in color).
So, yeah, it really depends on what kind of morph you go with.
