Ancestral Family Tree DNA Testing / Re: The Times wants your views: DNA ethnicity results
« on: Tuesday 09 February 16 14:25 GMT (UK) »
The Ethnicity test is only as good as the testers. Where does the determination of ethnicity come from. Either they have tested the remaining inhabitants of the area and somehow cataloged the findings without scholarly publication or the ethnicity is determined by testers who self report.
Where did we migrate from or where did we migrate to? Until the companies providing this information share how they have come to the determination it is just a working theory. Are they reporting on your haplo group information and not providing the same to the tester or are they reporting on the other 22 markers?
Since they ask ethnic origins for the tester maternal and paternal and report that info maybe it is a report based on that information. The ethnicity is still reported in percentage. It is unclear if this is a percentage of your genetic makeup or a report of the percentage of those matching you. Are 18% of those reporting from Asia and Asian, or are 18% of your matches saying they are from Asia origins, or are your ancestors 18% Asian?
What is the total that your DNA is being compared to? How many individuals are in your genetic pool? These are all legitimate question for which there is no answer is supplied. So genetic genealogy is still the paper trail you have.
