Geno 2.0 results

We can do that only if population is not very well mixed and Y haplogroups are recently coming from well known and defined ethnicities, and his autosomal DNA still could be mostly from that group. It is so rare that I can't give you a real life example. It is theoretical possibility only. The main issue is that ethnicity is a cultural phenomenon, not a genetic one. For example we can have a person living in Turkey having half of European genome, and this person is a patriotic Turk and Sunni Muslim. On top of it his language is actually from Central Asia, not from Near East, never mind Europe. This person also has not more than 10% original Central Asian Turk DNA. See, it is complicated even on autosomal level. His Y haplogroup could have come from Turkic, Near Eastern or European great, great... grand father. Complicated.

Not sure I am convinced by your answer LeBrok. I am not talking here about cultural ethnicity but genetic ethnicity like the ones based on autosomal dna in geno 2.0 ?

you said we can do that only if population is not well mixed. could you please be more explicit ?

For example you can do it for Polish people, but you can't for Americans, North and South, because there are too many different ethnicities recently mixed together. Most people in Americas are multiethnic on genetic level.

It is hard to do that for Italy either, even though it is very old country. Proportions of admixtures are quite different for North Italians, Sicilians and Sardinians, but they are all ethnic Italians. You would need to reduce ethnicities to local regions only. But what about people in big cities where ethnicities are mixed together. Who are they?

"Genetic ethnicity" works in some cases, also some deep clades of Y and mtDNA could be identified as prevalent in ethnic populations, but it won't let you speak ethnic language, wear ethnic clothes, observe ethnic ways.
 
But this complexity exist also at autosomal dna level. not sure this is the reason they dont use haplogroups.

lets say Population X has Hp A 50% Hp B 30% and Hp C 20%, same thing would happened with MtDna .... wouldn't this be more relevant in terms of ethnicity/origins of any population ?

In next door country population Y has hg A at 45% and hp B 50% and hg D 5%. In another country, lets say Z, A 60% D225% E15%.

Now 23andMe tested someone and he has hg A. What ethnicity should they assign to him Y, X or Z?

Well of course they would assign him to hg A (from an ancestry point of view).
 
let's hg A represents mainly east European that would be his ethnicity, same thing for sub saharan ...etc
Ok, so lets say that Y represents Poland and X represents Germany, and A is hg R1a. Do you think that every German with hg R1a should be called Polish (Slavic)?

For some deeper clades it make sense sometimes, and becomes obvious from historical perspective, and can point us to certain ethnic population expansion in the past. Check these maps, like R1b S21/U106 corresponding to Germanic expansion:

http://www.eupedia.com/europe/maps_Y-DNA_haplogroups.shtml
Again, keep in mind that this is in relation to ancient expansion only, and U106 won't make anyone German just by having one. We can only say that U106, 2% of DNA, had beginning in Germanic men 2-3 thousand years ago.
