I notice the very downstream snp Z141 is now available at FTDNA’s “advanced tests” (NOT advanced snp tests) for ordering. It might not be phyloequivalent to Z140 in spite of 1000 Genomes tree from limited tests. We need to confirm that. Reminder of who has turned out Z140+: I1-AS1, presumably I1-AS8, and the giant 14/22 complex including I1-AS5 and I1-AS6. There are a few I1-generics who also ended up Z140+ I believe. Representatives of all these clades ought to order Z141.
