> Even my brother and I share only ~50% DNA.

This is completely false. Any two random humans have more than 99% overlap by virtue of being the same species. It's even higher for brothers. We also share around 90% DNA with cats, dogs and elephants.

> I'm not too worried about it because it's never a 100% overlap.

This doesn't make sense. If they were equal, you'd be the same person except for environmental differences. Many applications don't need equal DNAs. E.g.

> About insurance companies, they're legally forbidden to use such data.

This is a very weak argument. There's a long history of companies doing illegal things, and even if it's illegal today it doesn't mean it'll be illegal tomorrow.

I think it was clear that @sedatk was referring to the 1% that separates him from other human beings, not the 99% that separates him from trees.

Yes, I thought it was clear. I certainly wasn't referring to the risk of incrimination of chimpanzees.
