DYS464 Expanded vs. Conservative Typing

[Rick T.]

Does anyone know what typing method FTDNA uses for DYS464? I have conflicting results on this marker from tests done by FTDNA and Relative Genetics. RG states they use the expanded typing method and reported 15,16,18,18 for my 464a, 464b, 464c, and 464d values. FTDNA reported 14, 15, 18, 18 - but I don't know if they are using the same typing method or not.

Thanks,
Rick

Have you asked FTDNA?

I found this on the Y-base website:

DYS464a-d
As of the 19th May 2003, Family Tree DNA are now reporting the DYS464 markers (which includes DYS464a, DYS464b, DYS464c, and DYS464d) in line with standard scientific nomenclature. All values have been reduced by 1. Thus a value of 15 now becomes 14.
