You'll get your widest from interracial households, especially when you get multiple generations of interracial mixing. So your African grandma, dutch grandpa, Chinese grandma and Indian grandpa type families are realistically going to be very far apart generically. And within that, historically people from cities will have more diverse genes than those from the country

Also: three of those grandparents could also be children of Genghis Khan.
