开云体育Hi Keith, Aaron,My father’s FTDNA results are Z63 [but not Z58], with the terminal at I-BY40648. His results are unusual, lacking in non-surname matches (a known cousin is 35/37 match). There are zero matches to his terminal SNP. I don’t have a good understanding of the haplogroup trees, but I had hoped through to identify a geographic region of origin for my male line. After looking at the results, it’s my understanding that the identification of regions associated with a haplogroup are based on the information provided by people who have tested. If that’s true, I would expect to find errors (due to incorrect family documentation) and large gaps (due to lack of participants) in the knowledge base. France, for instance is seriously under-represented in genetic test results. Can anyone suggest the implications of zero matches at the terminal SNP? I would also appreciate an insight in understanding how people from the UK would be downstream of a Native American. It flows like this, downstream of I-Z63:? I-Y6375
