Testing Candidates for L1333 SNP

Testing Recommendatons (March, 2013)

Candidates for L1333 testing (in order of testing priority and decreasing odds of testing positive) include:

1) For the fingerprint L1333, all testing candidates above 70 % (8 of 11 match or higher) should be tested - unless multiple submissions descend from the same oldest proven ancestor. With future additional test results available, additional fine tuning of the existing fingerprint may be required. See the L1333 spreadsheet under the DNA Results pull down menu for a listing of the eight good testing candidates.

2) For fingerprint matches between 50 and 70 % (7 of 11 and 6 of 11 matches), testing is still recommended until the true scope of L1333 is determined. The 130 testing candidates found in the DNA Results spreadsheet should be considered very speculative in nature but a small number of these submissions should test positive. Currently, both submissions that have been tested have tested negative for low fingerprint matches.

Only test for those candidates that are highlighted in green, blue or yellow. The higher in the spreadsheet, the more likely of testing positive for L1333. Since the L1333 fingerprint is only based on a small sample size of testing candidates, the fingerprint is currently speculative in nature and will require fine tuning with additional testing.
