SUMMARY OF SNP (October, 2012)

Classification of SNP: Probably "near private" - son of L513.

Estimated Breadth of SNP (speculative estimate of positive submissions) = 5 = 1 x 95 % (13 of 13) + 0 x 95 % (12 of 13) + 0 x 90 % (11 of 13) + 0 x 80 % (10 of 13) + 3 x 50 % (9 of 13) + 11 x 10 % (8 of 13) + 30 x 5 % (7 of 13). Five markers of the L9 fingerprint are very limited scope, so the true scope of L9 is very speculative.

Scope of Testing within Fingerprint: One positive and one test pending.

Dominant Surnames: Gilroy only.

Year that SNPs were discovered: 2008 (estimate).

Source of SNP: FTDNA - non-WTY discovery.

Baseline for SNP: Gilroy, FTDNA ID N56253, Y-Search ID F9KZK.

Number of Positive Tests: Only one.

Number of Negative Broad Tests: Around 100.

Number of Negative Tests within Fingerprint (above 70 % matches): None.

Possible Candidates (above 70 % match): Around 5.

Pending Tests (within Fingerprint): 58526, Goff.

ANALYSIS OF FINGERPRINT MARKERS

There are five markers that only have between 10 and 40 % of the submissions above a 60 % match. If these markers are actually part of the L9 fingerprint, the scope of L9 will remain very limited (around five submissions at most). If several of these marker mutations are later discovered to be post L9 creation, the scope of L9 could be two or three times more than currently speculated.

464c <= 16, 464d >= 18, 576 <= 16, 395S1a >= 16 and 511 >= 11 have many fewer matches above 60 % L9 fingerprint matches. With only one submission testing positive to date, these L21 off-modal mutations are very speculative in nature as they are only based on one submission. There are two negative tests between 50 and 60 % of the L9 fingerprint which implies that several of these limited scope L21 off modal mutations are probably part of the L9 fingerprint - but several may not be part of the L9 fingerprint.

TRENDS OF TESTING CANDIDATES

Note that the characteristics of known testing candidates do not appear to be a typical for L21 SNP where the number of testing candidates declines down to 70 % matches, remains very low for some time and then sees a sharp rise as non-L9 submissions dominate the under 50 % matches. The number of matches above 70 % are very sparse (only four currently). There is no typical downward slope from 100 % matches to 70 % matches which implies a more genetically isolated Y-SNP and higher than normal fingerprint matches may be required. Another explanation could be that the L9 fingerprint is not very accurate due to the five very limited scope markers included in the L9 fingerprint which may not be part of the actual L9 fingerprint.

ISOGG Status - Prove relationship of L9 to other L21 SNPs

Requirements for qualifiying L9 for inclusion on the ISOGG haplotree have not met been met to date. L9 may have difficulty in qualifying for the genetic diversity requirement, however, current testing within the L9 fingerprint is very limited to date.

Note: L69 has been removed from the ISOGG haplotree as an excessive number of independent mutations of L69 have been discovered. Also, L577 and L908 have not yet qualified for the ISOGG haplotree to date. All three Y-SNPs remain optional for ISOGG qualification but are listed to see how smaller scope Y-SNPs are related to other L513 Y-SNPs.

ISOGG Status - Prove genetic and surname diversity of L9

L9 does not satisfy either the 15 % genetic diversity requirement or the surname diversity requirement for inclusion on the ISOGG haplotree. Two submissions of L9 must have at least a genetic distance of 10 (15 % x 67 markers = 10). Only one submission has tested positive to date, therefore, these requirements can not be presently evaluated.

DNA FINGERPRINTS

L21 Off Modal Mutations:

Markers 1 to 37: 390 >= 25, 389-1 >= 14, 458 >= 19, 449 >= 31, 464c <=16, 464d >= 18,
456 <= 15 and 576 <= 16 (8 mutations).

Markers 38 to 67: 395S1a >= 16, 406S1 >= 11, 511 >= 11, 446 >= 14 and 617 >= 13
(5 mutations).

L9 Signature (L21 Project): 513-J.

Markers 1 to 37: 390 >= 25, 389-1 = 14 and 456 = 15 (3 mutations).

Markers 38 to 67: 406S1 >= 11, 446 = 13 and 617 >= 13 (3 mutations).

Note - there is no L9 signature but the only positive submission of L9 belongs to the signature 513-J.
