Use of Phylogenetic Trees to show distribution
Currently there are several different phylogenetic trees used in both scientific and popular (trade) literature. Using any one tree to show distribution within population groups is preferential and violates WP:NOR. Such usage also makes the article susceptible to WP:SYNTH violations.--RebekahThorn (talk) 12:43, 16 November 2010 (UTC)
Haplogroup Q Y-DNA in Americas
- Dominance is a loaded word. This is especially true in population genetics. It would be true to say that several Q-M346 subclades were part of early migrations to the Americas and that Q-M3 is by far the most common one in current descendants of these early migrants.
- If anyone cares to go back over specific papers and sources, that would certainly be nice. :-) --RebekahThorn (talk) 17:03, 8 November 2010 (UTC)
Apparently there is a sublineage of Q1a3* (Q-M346) which is considered a Scandinavian (and possibly Russian) haplotype & subvariety. According to an admin from the Scandinavian DNA project at FamilyTreeDNA the group (or 'Group 1' of such a group) is distinguished by DYS385a-b=13,12 and DYS392=14 in a 12 marker STR test. Since in Europe this Y-haplogroup seems to be associated with jews, it might be of interest to make mention in the article of where exceptions to this exist. From my purely speculative mind of (regarding synthesis & original research that shouldn't belong in the article) I'm driven to think of the distinct phenotypal minority groups recognized by certain obsolete schools of anthropological taxonomy in Scandinavia, namely the "Standid" & "Tydal" types (probably isolated non-lappoid population pockets from some time in prehistory).

- Haplogroup Q1a3-M346 has also been found in Pakistan (Pashtuns, Makrani Balochs), India (Vellalars, Halbas, Uttar Pradesh Brahmins), and Tibet. I'm afraid that examples of haplogroup Q from many parts of the Old World, including Europe, have not yet been tested for M346; it may turn out to be the most widespread subclade of haplogroup Q in the Old World as well as in the New.

- Is there any more information about where the numbers for Norway and Sweden come from and more specifically which ethnic groups were tested? Were the Qs found among ethnic Norwegians and Swedes or Sami, for instance? Maitreya (talk) 14:09, 20 November 2012 (UTC)

Deletion of Published Studies
I have removed the frequency of 9%, referenced to Regueiro. The 2006 study sampled only 33 individuals from the Northeastern tip of Iran (which may have even included Iranian Minorities). I've replaced it with the 2004 and 2009 studies by Ivan Naszide, which consist of a much broader sampling. —Preceding unsigned comment added by 22.214.171.124 (talk) 03:27, 14 November 2010 (UTC)
- Please do not delete published studies. Rather add additional studies and note the limitations of each.--RebekahThorn (talk) 12:43, 16 November 2010 (UTC)
- 1) To make such edits, I guess it's better to register and introduce yourself.
- 2) From where do You have information that the "North Iran" sample is actually from the Northeastern tip of Iran?
- 3) Regueiro2006 nowhere says "Persian". It uses the terms "Iran" and "Iranian". Which population was studied is really unclear: whether it is Persian, speakers of languages of the Iranian branch or different ethnicities of the country of Iran. СЛУЖБА (talk) 23:15, 28 February 2012 (UTC)
See  "Ancient links between Siberians and Native Americans revealed by subtyping the Y chromosome haplogroup Q1a" which is a new article in the Journal of Human Genetics. "Q1a*-MEH2 likely traces a population migration originating in Northeast Siberia across the Bering Strait." However, this is a relatively late connection, "Despite the low coalescence age of haplogroup Q1a3*-M346, which is estimated in South Siberia as about 4.5±1.5 thousand years ago (Ka), divergence time between these Q1a3*-M346 haplotypes and Amerindian-specific haplogroup Q1a3a-M3 is equal to 13.8±3.9?Ka, pointing to a relatively recent entry date to America. " and "Although the level of STR diversity associated with Q1a*-MEH2 is very low, this lineage appears to be closest to the extinct Palaeo-Eskimo individuals belonging to the Saqqaq culture arisen in the New World Arctic about 5.5?Ka" Dougweller (talk) 16:37, 9 July 2011 (UTC)
- I completely fail to understand the sentence "Despite the low coalescence age of haplogroup Q1a3*-M346, which is estimated in South Siberia as about 4.5±1.5 thousand years ago (Ka), divergence time between these Q1a3*-M346 haplotypes and Amerindian-specific haplogroup Q1a3a-M3 is equal to 13.8±3.9?Ka, pointing to a relatively recent entry date to America."
