开云体育A rather simple explanation for the I-Y6375 amerindian part is that one person hasn’t the heritage he thinks, Somewhere in his line is an European ancestor. That is always the case when using user submitted information. The best with this is that the user now see that this is probably not right ?
? Fr?n: [email protected] <[email protected]> F?r E Avery ? 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 Amerindian ancestry >?I-Y13945?UK ancestry >?I-BY40648 (my father) ? Thanks in advance for any thoughts or suggestions! ? Best, Eileen ?
