The empty slot was brought up in a scenario where we would call it Hemizygous, we are all just theorizing right now, but my point was you could still get normals if that was the case if the "empty slot" could be passed in a Hemizygous case. We were just trying to find something similar else in the genetic world, I dont think whats going on would be considered Hemizygous, but it's the closest thing I've seen so far in the real genetic world. What I haven't looked into was if Hemizygous can be caused by other factors rather normal conditions.
also you would get mojaves in that mix also. there wouldn't be any normals without the non-functioning gene.
