    Sprinkle in a little incest and we are good to go.

    I also have no idea, I thought it was all halves of halves.

      You can get some odd fractions by two parents having similar lineages. Like, if your mother is Irish, and your great-grandmother on your father’s side is Irish, you would be five-eighths Irish. I’m having trouble finding a combination that gives you thirds, though.

        Doesn’t exist, 3 is prime. No combination of 2^-n will get you a 3 in the denominator.

        …unless somewhere along the tree there’s a person who shows up twice.

          Gotcha. Three-eighths is roughly one-third, so I guess that? One-quarter German on one side, one-eighth on the other?

            That rounding error would be small enough that most people would consider it less bad than incest, maybe.

      It is a rounding and reduction of genetic markers.

      21/64 Germanic markers equals 1/3 German in speech because everybody hates the twenty-one sixty-fourths German guy.
