This may not be relevant, but I once calculated that at the 7th generation there is only a 50% chance of inheriting DNA from an ancestors. This is because DNA breaks are chunky and at a certain point you can just lose all the DNA from an ancestor . So when you go back you are actually only related to a subset of your ancestors

Interestingly 7 generations is also the max number of generations in a human lifetime for most people

  • Great Grandpa
  • Grandpa
  • Father
  • Me
  • Daughter
  • Granddaughter
  • Great granddaughter

I've always wondered if this is fine tuned by our DNA crossings
