I know absolutely nothing about genetics as it relates to race and ethnicity, but I would be highly skeptical that there are a "german subtype" of women. There should certainly be no conclusions drawn from the fact that you know one person who also shares many traits with Summer along with the same ethnic background. Perhaps there are some features considered distinctive of many females of German blood, but saying there is some subtype seems a bit drastic. My Grandmother and father were both born in Germany maybe I should ask them.
I agree the word subtype is a bit too strong, I searched for words honestly hence my usage of quotation marks. Moreover the girl was Hungarian body and soul and could not speak a word of German or other related languages except English of course so her heritage is from a long ago and she isn't exactly a pure german ( Summer neither I guess). I just wanted to implicate that the gene combinations source may be from german heritage and thus it may be more likely to find in their population.
Maybe their similarity is just a coincidence but they are very similar like if they were relatives and the only link I can find between them is the german heritage.

Maybe they know more. This thing bugs me for some time but I'm not a gene specialist so I have no clue how to know more about this.
If you are a gene specialist and reads my posts, please respond
