Overview of Project Subgroups
This project uses a ‘dynamic’ subgrouping process which utilizes all available information (SNPs, STRs, surnames and known genealogies) to group together testers who share a significant common YDNA ancestor.
Key features include:
- Testers who are very likely to be related within ‘genealogical time’ (last 500 years or so) or descended from a surname founder
are grouped together
- ‘Outlier’ individuals and small groups are usually grouped with their closest relatives (even if distances are outside the standard
limits for matching)
- Average grouping size is ~9-10 members
- ‘Colorized’ results pages show group/surname STR signatures and variations
- New members are grouped immediately (usually within 24 hours of joining)
- Groups are reviewed regularly to consider the impact of new branches and new members
- The process is flexible and variations are considered for exceptional cases
Subgroups are organised into 12 major sections as follows:
A
Groups
Members are confirmed or predicted SRY2627+ and have DYS490=10. These groups are confirmed
or predicted CTS8289+ and Z208+ which appear to be equivalent to the DYS490
12->10 mutation.
B
Groups
Members are confirmed or predicted SRY2627+ and Z205+ but Z208- and/or have DYS490=12.
C
Groups
Members are confirmed or predicted SRY2627+ and either FT141876+ or Z200+. Z205 is either negative or not yet tested.
C80-C89 members are confirmed
SRY2627+ and have DYS490=12 but no downstream SNP results.
C90 members are
SRY2627+ but don't have a result for DYS490 or any downstream SNP results.
C80-C90
are encouraged to order a Big Y test to refine their placement in the project.
D
Groups
Members are confirmed or predicted ZS312+ and/or Z267+ but SRY2627-.
E
Groups
Members are confirmed or predicted ZS312+ and Y19152+.
F
Groups
Members are confirmed or predicted ZS312+ and BY3214+. Those with DYS439=8 are confirmed or predicted Y36951+.
H
Groups
Members are confirmed or predicted ZS312+ and FGC39110+.
J Groups
Member are confirmed or predicted L165+.
L Groups
Members are Z46513+ and negative for L165 and ZS312.
M Groups
Members are CTS4188+.
N Groups
Members are Z198+ and negative for Z46513 and CTS4188.
Q & R Groups
Members have incomplete SNP test results and cannot be placed in one of the above groups. Big Y test recommended.
