Most morphs are first found in the wild. Designer morphs are not, but they are just two morphs combined in captivity through breeding (ie albino spider).

It has happened that two seemingly normal animals bred together in captivity have produced morphs. I don't know about ball morphs, but the T+ albino BCIs originated that way.

I don't know about the second question.. I often wonder the same thing.. how did the first albino originate..? Were the parents hets..? If so, where did they get the mutant gene?
