It doesn't really matter though. How they choose to live is probably just indicative of how they are raised. Since anyone, Human or Zentran/Meltran can be a maclone or a miclone if they want to, it's probably just decided by what culture they're raised by.
It's obvious that Ranka, Michel, and even Max's family were raised as Humans, and so they're almost always micrinozed, whereas it seems that Klan, for example, was raised as a Meltran, albeit a "modern" day one where battle isn't everything. So she was usually macronized prior to having to interact with her micronized subordinates.
