SUMMARY OF SNP

Classification of SNP: Private. L908 is a son of L513 and L909 is currently redundant with L908 (only one tested positive to date). Y-Search query only found one testing candidate above 60 % fingerprint match, so these SNPs could be very narrow in scope.

Estimated Breadth of SNP (over 70 % match): only two submissions found.

Scope of Testing within Fingerprint: (December, 2011) - Average - only one has tested positive via the Walk the Y test. Only one possible candidates (over 70 % match of DNA fingerprint).

Dominant Surname (positive): Roberts (1).

Year that SNPs were discovered: 2011 (estimate).

Source of SNP: FTDNA WTY - Roberts, FTDNA 210379, Y-Search - not found.

Number of Positive Tests (March, 2012): One known.

Number of Negative Broad Tests (March, 2012): Only four outside of the 70 % match of L908 fingerprint.

Number of Negative Tests within Fingerprint (over 70 % match): None.

Possible Untested Candidates (over 70 % match): Only one.

Pending Tests (within Fingerprint): None known.

DNA FINGERPRINTS

L21 Off Modal Mutations:

Markers 1 to 37: 385a >= 12, 439 <= 11, 459b <= 9, 449 <= 29, 464a <= 14, GATA-H4 <= 10, 456 <= 14, 607 >= 16, 576 >= 19 and 570 >= 18 (10 mutations).

Markers 38 to 67: 531 <= 9, 406S1 >= 11, 413a <= 22, 534 >= 16 and 617 >= 13 (5 mutations).

Most Distant Positive Test Known (67 markers)
(from MRCA of positive submissions - not WTY):

Only one tested positive to date (WTY submission).

Closest Negative Test Known (67 markers)
(from MRCA of positive submissions - not WTY):

Kelly (41466/GXJEB) - L908 fingerprint match (7 out of 15) and GD = 14.

DNA Signature (L21 Plus project): None.

Markers 1 to 37: None found (0 mutations).

Markers 38 to 67: None found (0 mutations).

Note: There was only one good testing candidates that have not been tested. Any lower odds candidates (50 to 60 % fingerprint match) would be very speculative since there was only one submission found with greater than a 60 % match to the L908 fingerprint.
