I personally would be HAPPY and willing to supply a DNA sample of my daughter. I work in the criminal justice field, so you have to know my mind goes crazy with all the scary possibilities that can happen. DNA is the only thing that stays consistant to ONE person for life. Looks can be changed. Fingerprints are expected to grow a bit and aren't always left behind (there has to be oil on your fingertips to leave prints). But think about it: We lose TONS of hair a day. We drink and eat everyday. Everyday we leave some of our DNA behind. If the child is ever abducted or lost, at least a sample left behind can be ran and compared with the DNA on file. And, Lord grant that this is never the outcome, if a body is beyond recognition (burned, badly decayed, etc), DNA could AT LEAST give the family knowledge that they shouldn't expect this member back home. It's a small bit of closure, but it's more than what a family would have before the DNA test results. Like I said, I would gladly give a sample from my daughter. Better to be safe than sorry.
