If I were to classify the genetics of the world into 3 separate categories, I would categorize them as Eurasian(Excluding East-Eurasians), Sub Saharan African, and East Eurasian. Now, there are some obviously large distinct gaps between these groups, but these can give you a general idea of which races share the most of the core DNA. Additionally, there are some regions which share a different genetics from these 3 distinct groups. I’ll try to write about this again to provide some clairification and insight into this.
