With all the controlled eugenics programs, forced repopulation and general cultural genocide performed by both the Reich and (less so) the Empire, the majority of humanity has lost most of its genetic identity. Of course, this was intentional, in an effort to make the cultures of the Axis the most dominant on the planet. Also, the philosophy was that if you isolated the degenerate genetic lines, they would eventually die out, while the Aryan lines would flourish. Unfortunately, true science trumped ideology and the so-called untermensch have flourished as well as the Aryan ubermensch, if not better.
