It's made pretty clear the moon race are generations removed from identifiable earth ethnicities and grow up in assigned families of people with seemingly unrelated genetic traits. I always assumed there was some sort of forced genetic diversity stuff going on, to stop genetic stagnation in a smaller population. I don't know if that's actual test tube baby shit or the kids are simply taken away from their birth mothers who went through selective breeding decided by moon bureaucracy or what.
Either way I'm pretty sure everyone from the moon is some vague mystery meat with a few random traits thrown in (Loran's feather hair, Gym's lack of eyebrows, whatever the fuck was going on with Marybell's eyes).
