Because of continuing research, the structure of the Y-DNA Haplogroup Tree changes and ISOGG
does its best to keep the tree updated with the latest developments
in the field. The viewer may observe other versions of the tree on the Web. Email
Alice Fairhurst if the differences need
clarification or if you find any broken links on this page.
L L855, L863, L878, L879, M11,

Private SNPs are being removed from the tree and placed in the following category:
Private SNPs - After investigation these SNPs have not met the population distribution criteria for placement on the tree:
either too few confirmed positive testers have been found OR multiple confirmed testers were confined to a single surname or to a
small group of related males.
- PK3 is downstream of M357. Listed 6 August 2012.
SNPs under Investigation - Additional testing is needed to confirm adequate positive samples
and/or correct placement on the tree.
- Page113 and Page116 are downstream of Page 121.
Listed 1 November 2011.
- Page6 is parallel to Page 121. Listed 1 November 2011.
- L877 are
found in L2. Listed 19 November 2011.
- L864, L865, L866, L867, L868, L869, L870 and L877 are found in L2,
negative in L1. Listed 19 November 2011.
- L1304, L1305, L1306 and L1307 are found at approximately M357. Listed 7 October 2012.
- L147.6 is found at approximately M317. Listed 1 December 2012.
- L193.2 is found at approximately M61. Listed 4 March 2013.
Y-DNA haplogroup L is found primarily as sub-group L1a (former L1) in India, Southern Pakistan
and Sri Lanka. Paragroups L1b* and L1b1* (former L2*) and sub-group L1b1a (former L2a) are found at low frequencies
in the Middle East and Europe. Sub-group L1c (former L3) is found mainly in northern Pakistan, northern
India and west-central Asia.
- M22 and M295 were considered equivalent to M11, M20, M61 and M185 in previous versions of the tree. In May 2011
a small group of members of the Y-Haplogroup L Project were found to be negative for all known subgroup SNPs of L
and in addition M295- despite being M20+ and/or M61+. Further testing has confirmed that M22 is also negative in
this group. The tree has been revised to reflect this discovery. A new SNP L595 has been discovered in a member of
the M22- M295- group and has been confirmed in a second member. This SNP therefore designates a new subclade: L2.
Several new SNPs have been discovered in L2 and are being investigated.
- Identical SNPs that were discovered separately are listed in alphabetical order, not necessarily in
the order of discovery, and separated by "/". Example: M61/Page43.
