  • An entire cluster of us in J2f1 have 13.1 at DYS464b. FTDNA reports only whole numbers from their standard test, so 13.1 is rounded down to 13.

    In your case, 14.3 was rounded up to 15. Why up? Because the .3 isn't an actual decimal value; instead it means you have 3 (of the 4) bases in that repeat, which is more than half.

      It is a shame they ever rounded these values to the closest whole repeat value. Such cases of partial repeats would be extremely helpful in surname studies or in evaluating close haplotype matches. It seems reporting partial repeat results would no more difficult than reporting the rounded results. Too bad most folks won't order the advanced 464 test (or other applicable markers), so we'll never be able to confirm the real values for most folks in ysearch, etc....unless of course ftdna corrects the original reported results for all markers with partial repeats (oficially hinting and begging here).
