Understanding and ordering the 37-marker test
With hundreds of Surname Projects, and many of them having 3-digit members, Family Tree DNA
had a good reason to develop a new 37-marker test that would allow those families to add more information to their research. This information will eventually help identify splits in the family lines as well as the potential time when those splits happened.
Considering that the primary purpose of
genealogy is to link with relatives - ideally, relatives that one can
draw some version of a paper trail around - FTDNA is now bringing to
the market the world's highest resolution test that will contract the time
estimates to the Most Recent Common Ancestor (MRCA)- see chart.
Who should order Y-DNA37? This refinement of our existing
25-marker test offers the following advantages:
-
Substantial reduction in the Most Likely Estimate (MLE) to the MRCA.
- Constriction of the tail of the curve to a time frame that
approximates the adoption of the surname by families in the British
Isles.
- An invaluable aid for Surname Projects
who have found 23/25, 24/25 and 25/25 matches
and now want to gain a better snapshot of the actual breakdown of
the family tree.
Should new customers order the new 37-marker test? Now you have a choice, 12,
25 or 37 markers. All tests prove the same basic question: are we related? However
the parameters of WHEN are superior with Y-DNA37. We anticipate
that the 37-marker format will allow us to answer other interesting
Genetic Genealogy questions in the future. Because the University of Arizona (which has the
laboratory that we use) keeps the DNA on file in a locked
refrigerator, if you decide to start with a 12 or 25-marker test, you may
return to our site and upgrade your test at any time in the
future.
