What does it mean when someone has good genetics for bodybuilding?

Generally speaking, you have to begin with a good bone structure...meaning, shoulders are broad, waist thin, legs not too long or short. Then, we either have a pre-disposition for lean muscle mass or we don't. Being "big boned" and or stocky" doesn't usually translate well to becoming a body builder, but could translate well to being a power lifter for example. Having a high metabolic propensity is also favorable...meaning, you can add weight and take it off quickly when needed.
