SUMMARY OF YSNP (May, 2016)

Classification of Branch: Near Genealogical - son of FGC5660.

Known sons: None

Estimated Breadth of branch (speculative estimate of positive submissions) = currently only five but many are unknown.

Scope of Testing within Signature: No testing within signatures other than Big Y tests.

Dominant Surnames: Moloney (2), Smith (1), Costello (1) and Phyffe (1) - many more could be added when true scope of branch becomes better known.

Date that branch was discovered: Unknown.

Source of Branch discovery: Two FTDNA Big Y tests (249892 and 393961).

Number of Negative Broad Tests: Around 40 (all Big Y results).

Number of Negative Tests within Signature: None known.

Pending Tests (within signature): None known.

ANALYSIS OF CURRENT DC63 HAPLOTREE

I manually separated around 86 L226 submissions and then used the SAPP tool to generate a chart which most of DC63 does not appear to be accurate upon inspection. This branch of L226 has several issues preventing the complete descendant chart of DC63:

1) Both submissions that tested DC63+ have no common YSTR signature, so two independent signatures were used. When manually inspecting these two signatures, no pattern of YSTR evolution was apparent from manual analysis, so the input to the SAPP tool was probably lower quality than other branches.

2) The current limit of around 100 submissions really limits the accuracy of the desendant chart for this particular L226 branch. The SAPP tool did generate a chart but DC63 was much larger than reality and many submissions were declared positive for DC63 even though they shared no marker mutations with either NGS tester.

3) However, the signature associated with the Smith (249892) submission had a three marker signature that was able to reveal three good testing candidates. The branch created by SAPP for the Costello (393961) signature was only a two marker signature but one marker value was unique to this NGS tester. The SAPP tool generated a pretty large branch based on only one mutation which was removed from the final graphic due to its inaccuracy. The SAPP tool also generated many of branches under DC63 that did not share any L226 off modal values with either of the two NGS testers and those were removed as well.

Once the limits of the SAPP are increased and more testing results are available (both YSTR submissions and YSNP testing), accuracy will greatly improve.

OTHER FUTURE YSNP TESTING

No pending tests are known.

DC63 Haplotree

The link to haplotree chart is the best way to look at the evolution of the DC63 haplotree. It is visually much easier to follow than spreadsheets and is very close to a genealogist descendant tree charts that genealogists already are well trained in analyzing:

Haplotree of DC63

This summary will attempt to priortize testing and explain why each test is beneficial to the the verification of the DC63 branch.

Here are the priorities for testing:

1) The scope of DC63 is not well known and it is important to determine its scope in order to intelligently know who should test NGS tests and who should order individual YSNPs.

2) It is also recommend that all current submissions that are predicted DC63 positive should test only DC63 for $17.50 from YSEQ. Once a full analysis can be completed (improvement in SAPP limits, further YSNP testing and completed view of all of L226), many more submissions will probably be moved under DC63 and will become testing candidates..

3) Current predicted DC63 positive testing candidates include:

118295 Moloney
277345 Moloney
225685 Phyffe

4) In the future, once the status of DC63 is confirmed, this section will be expanded to include testing recommendations of private YSNPs assiciated with DC63.
