I consider myself an example of positive mutations (I'm not a Ninja Turtle). My dad has rather fragile bones. Mine, on the other hand, are quite strong (I've never complained) and I've never broken anything, even though others have broken bones in similar situations:smile47:.
What about your grandparents? How strong were their bones? As far as I know, pathologies are passed down through generations, including positive ones, although less frequently!
As for the spirit (soul), I'm not sure how much of it I inherited from my ancestors, although there probably is some. These qualities have simply adapted to the surrounding world, so they seem to be my individual traits.
