Just checked for my Big Y matches -- 0, none. I'd understand not matching on my terminal SNP (BY4064); it's bound to be a small group. But that's a couple of levels below Z253, a larger group. I just...

New R haplogroup classification moots an SNP test?

I'd advise canceling the SNP test. Phylogenetically, P25 is R1b1; M269 is R1b1a2. P25 is upstream of your R-M269 prediction and if it goes through, you'll be stuck with the label until you test M269...

I think the explanation is semantic confusion. The study you referred to lumped the people from (present) Denmark in with Anglo-Saxons but today we call Denmark part of Scandinavia.

I support Ann's advice; report it and ask for a review. It's worth being sure. If those three markers really are nulls (deletions) that's rare. In my project, with >600 Y-STR results, we've seen only...

Really, no matches in 4 years

Presumably, you're talking about a Y-DNA STR haplotype. Almost no one but FTDNA is testing those now. (The exceptions are small labs without match-searching resources; 23andMe and Ancestry test...

Y chromosome mutations

No. The Y chromosome is carried by the male father's sperm and, unlike other chromosomes, doesn't recombine with its partner -- an X within the female mother's egg.

Y46 to Y37 Transfer Tracking

I'm seeing some project members have difficulty with transfers of Y46 to Y37. This requires a new sample to be submitted for the additional markers, but progress seemingly isn't tracked. It's as...

Project Admin Guidelines

It seems fairly clear that the authors of these guidelines have little concept of what administering a DNA project entails; some of the items have not been thought through sufficiently. Perhaps, more...

No matches on Y DNA

By "no matches", I'm guessing you mean none appearing on the search list. To some, "match" is not a yes/no matter, but one of degrees.

It's possible, of course, that FTDNA has tested no one else...

Disappearing Results

We recently saw some results disappear from the Taylor project database, about two dozen of them. One day they were there, a month later they weren't. An inquiry didn't produce an explanation as to...

More Statistics

I'd like to see more done with the probabilities on the website. This was a valuable feature of Relative Genetics, before it was taken over by Ancestry.
