What you&#x27;re claiming about the privacy of DNA isn&#x27;t strictly true. You&#x27;re correct that, aside from mutations, we share all of our alleles with one or the other parent, and about half of them with full siblings, etc. But this information in itself doesn&#x27;t enable one to predict the exact composition of your genome, which would be needed to form a predictive model of your body. It would still be possible to, say, link your DNA to that found at a crime scene, but you still sacrifice something by giving it up.<p>I have little hope that we will maintain this form of privacy, but that isn&#x27;t to say nothing has been lost.
