This table appears to be entirely original research. Dougweller (talk) 08:21, 6 October 2013 (UTC)Reply Not at all. It merely cross-references differing nomenclature over the years for the same Y chromosome haplogroups and their subclades. ISOGG's Y-DNA Haplogroup Tree has been cited by dozens of peer-reviewed scientific papers. That's one of the explicitly mentioned criteria in the WP:SCHOLARSHIP policy. Nathanm mn (talk) 21:56, 15 October 2014 (UTC)Reply I have tagged the missing references with "clarification needed." Can you or somebody find these references please? They are also missing in at least dozen other pages on Wikipedia. Cheers, Kautilya3 (talk) 09:21, 14 October 2015 (UTC)Reply This article is based on the 2002 Y Chromosome Consortium article entitled A Nomenclature System for the Tree of Human Y-Chromosomal Binary Haplogroups and reports the adjustments/modifications done since then. And without such a conversion article about the difference between the long hand and short hand reporting of YCC haplogroups, one would be easily confused.
