Another Big Y, another 10 SNPs: Updated I-L160 tree

Click here to download our January 17. 2017 tree for I-L160 (part of I-M26 "Sardinian")

Thanks to a new Big Y, we now have information about a new branch that's approximately 3,000 years old, it's called I-A20341. In total 9 or 10 SNPs define this branch. Two of them are available for individual testing at YSeq.net: A20341 and A20342. Another SNP occurred independently in the I1 haplogroup: A18076

There have been two Big Ys for I-A20341:
--a Canadian man with paternal ancestry from Portugal, he has no STR marker matches
--an American man with paternal ancestry from southwestern Germany. He has several STR matches who have ancestry from Germany and Switzerland, including some men born in Switzerland

There is also a Mexican-American family with markers that show similarities to the German/Swiss group
