I've no idea but if it's a genetic defect it's sure as hell a better one than the kind that we got.
I often picture a future where we have long uncovered all the mysteries of male pattern baldness and genetically engineered a breed of humans that are completely resistant to any kind of baldness. NW1's walking with their heads up high everywhere. Thick, awesome hairstyles wherever you look. Being able to get a new dope haircut every week if you so choose, even at 60 years old. It would be like a big f*** you to nature. Second only to beating aging altogether.
