J2 in Sicily

[Jason]

I am trying to figure out the historical group that would "most likely" yield a Y-DNA result of J2. The family came from western Sicily, inland a little bit.

So far, Phoenician, Greek, and Arab are the most likely candidates. Anyone know of a study or want to hazard an educated guess?

According to that website, 25% of Greeks share the J2 haplogroup in their Y-DNA. Although that percentage may seem low, it's the most common one among Greeks. I'm also a J2.

I that the J2 group is currently under represented in the Y-DNA databases, my step-father is J2 and he is from a small town near Pescara Italy.

he has 0 matches in the REO database and his results cannot be uploaded to the Genographic project without further SNP testing.

Dear EBurgess:

What does SNP testing have to do with the Genographic project? Are you required to have a SNP result before you can upload Y results?

I have no matches for my mtDNA results and had no difficulty uploading those results to the Genographic Project.

Just curious.

I ran into the same problem as EBurgess. On the basis of my strs I was tentatively classified as J2. All my exact matches were J2 including a possible relative from my father's town in Lithuania. However my near matches were listed as J not J2. I had mentioned this confusing picture to FTDNA when I first received my results. Now it turns out that there must be an unambiguous picture before the results can be submitted to National Geographic. My next step will be to get the SNPs.

Dear John,

As it turns out The Genographic project has two datasets. One group is fully tested with SNP (single nucleotide Polymorphisms) as well as the STRs we use (Y-dna 12). The other group is from the so called public participants. These are just the Y-DNA and Mtdna.

So some Y-dna results are considered unambiguous such as mine which is R1B1 and therefore very common, the degree of certainty that I am R1B1 is considered high. For example I have 25 exact 12 marker matches and loads of matches in the REO (recent Ethnic Origins).

Also I think there is more data for some Haplogroups than others. I am not certain whether this is because some haplogroups are less common or whther there is just much less participation from these groups in the study.

I have to admit I am slightly confused as to how a scientific project can have two different datasets, STR and full-SNP. My understanding is that Spencer Wells and his group would like to refine the rough outline of the global human genetic tree.

Take what I say with a grain of salt I got most of my info 3rd hand.

Regards,

E.

Josh,

As I have posted elsewhere on this site, the whole J and J2 business is extremely confusing. Evidently they share many STR haplotypes. I have many exact matches that are J2 but when you get even one step off it is evenly split between J and J2. I suspect that there is more to learn here, but I had a SNP test to confirm my J2 status. I believe that part of the purpose of the Genographic project is to resolve issues like yours.

Sorry,

I have not been to the forums in a while, I just noticed a dedicated Genographic forum and also some of the answers are there as well.


I too will probably pay the extra and get the SNP tests done for my step father, just to be certain...
