While doing research for a friend who has Scottish ancestry, but shows a Slavic (R1a) haplogroup, I began looking for evidence that there were lineages other than the typical I, or Grecian/Mediterranean haplogroup most common in Scandinavia. Swedish researchers have found that about 12% of the population there is of Slavic descent (http://www.nature.com/ejhg/journal/v14/n8/full/5201651a.html), and a similarly large percentage of the population in Norway.
What does this say for racial purity, as traditionally defined by many Germanic traditions? Nonexistent. Having Slavic, or African ancestry enriches our heritage, and does not either define or detract from it.
