12, 37 & 67 Marker test performed by Family Tree DNA

y-dna June 10 2019 

DNA that is carried on the Y chromosome can only be passed from father to son.  The Y-DNA for all of the above tested males descended from Heinrich Frey who was born in Germany in 1673.  In the 477 tests that are reported above, there are 464 exact matches.  Of notable interest is the fact that the mutation on marker 464a occurred from Heinrich to either his son John or Benjamin.  The question is whether the mutation was to son John or to son Benjamin.  This question can be resolved if additional descendants of the other sons of Heinrich show marker 15 then the most likely mutation occurred to son Benjamin.  If these tests show marker 14, then the mutation occurred to son John. 

Mutations randomly occur in nature and are shown in red, above, as a mismatch.  Except for allele marker 464a, it is impossible at this time to tell at which generation level, or with whom, these mutations occurred without testing all of the living Frey, Fry, Frye males that descended from Heinrich Frey.   All of the above tests were performed by Family Tree DNA and the allele numbers in pink are more commonly mutated than the allele numbers that are not highlighted.

If you are a male with the surname of Frey, Fry, or Frye and want to know if you are descended from Heinrich Frey, y-DNA testing should be able to tell you definitively.  At this time only Family Tree DNA is performing y-DNA tests.  www.familytreedna.com
