  About 0.3% of people have identical twins (https://en.wikipedia.org/wiki/Twin) from a quick look at the Wikipedia page, so at least that! How would you even measure how much someone looks like you though?

  Apparently, both Facebook’s facial recognition system, and human eyes, can tell if two different images are of the same person about 97.5% of the time, which doesn’t actually sound like that much. Maybe people look more alike than I thought!
  
  That’s the best I can do, because I’m not an expert in this area!
