I received my J2 deep clade results from FTDNA indicating "negative" results for all subclades downstream of the J2 clade, M172. According to my updated haplogroup tab, I am "J2" with no letters, symbols or numbers thereafter. This is disappointing to me as I hoped the testing would reveal something deeper about my ancestral origins.
Further, I have seen a reference in a recent scholarly paper to a SNP identified as M410. The authors claimed that the research suggested that any J2 who tests M12- (as I did) must necessarily be M410+ since no one who was M172+ has yet been found to be both M12- and M410-. Apparently FTDNP does not test for the M410 SNP, but another testing company does. Is this further testing worth exploring, or can I at this point safely conclude that I am M410+ without further testing?
I note that FTDNA does not include M410 in its J2 tree, but M410 appears in the isogg.org J2 tree as defining the revised subclade J2a. Does this indicate that FTDNA disputes the validity of M410 for purposes of distinguishing the subclade? If not, why isn't FTDNA recognizing and testing this SNP?
Any thoughts, anyone? Thanks in advance.
