Response to drugs, skin complexion (yes, it has some relevancy), skin "thickness" (or whatever they call it, ref. leather skin on GH wrecks), vascularity, muscle shape, bone structure, joint size, constitution (no point in being a BB if your body can't stand teh drugs) and so on.
Genetics influences many things.
Sperm.
Vagina.
