Hello Andy,

Why don't you provide some insights on your results ? STR results tend to overlap when not enough markers are done. I have ysearch ID : 9UTFU and you can easily verify that, in my case, I have no exact match on the first 25 markers and I did more than 80 ... Besides, you can perform a SNP test (called UEPs in your citation) ; this is giving you another piece of information to which group you belong. When you understand the principle you'll find out that you have a fantastic tool at hand. The only problem I would say is that it costs money !

Didier

> It is important to note that, unlike for UEPs, there is no guarantee that two individuals with a similar Y-STR haplotype will necessarily share a similar ancestry. There is no uniqueness about Y-STR events. Instead, the clusters of Y-STR haplotype results inheriting from different events and different histories all tend to overlap.
