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.
Sprinkle in a little incest and we are good to go.
I also have no idea, I thought it was all halves of halves.

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

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.
