How to avert bogus results and lack of volunteers when obtaining GEDmatch Oracle database?

[reboun]

If you don't know, GEDmatch calculators' Oracle results are something like this:

I basically shows a person's DNA results' proximity to the DNA of some ethnic groups. My question is, how do they determine the ethnic groups' DNA results?

If there are volunteers, the volunteers might easily lie about their real ethnicity and distort the database. Or, they might not have any volunteers from some ethnic groups and the database of those ethnic groups could not be represented in the Oracle.

So, how do they avert these two possible undesired situations?

Why do you use vulgar language towards me? You have been reported.

I do not have any identity crisis nor projecting any issue onto other people. You might not know, most Bosniaks identify as Turkish and they are considered as honorary Turks by non-Bosniak citizens of Turkey also.

"Stop asking questions about Paris-born Congolese not being included in a Parisian average." I have never told something that sort in the question, please read it again.

So now TA deletes swear words. It didn't use to be like that. I could say fuck, shit, nigger, pussy, etc. with impunity.

Yes, your questions are retarded and all in the same vain. You think all people born in a country and holding the citizenship should be included in genetic averages. And you keep asking similar nonsense over and over again.

Not as bad as you.
