Z6405: new Italian subclade under Y934

[jmestres]

A new subclade from Y934 has been defined in version 4.09 of YTree. It's been labelled as Z6405 and it is currently composed of two individuals from Italy.

Overall, Y934 emerges as a "split branch" from its origins somewhere in Central Asia, with some subclades migrating north-west (Russia, Turkey, Poland, Bulgaria, Italy, Spain, and Britain), whereas others moving south-east (Kuwait, Qatar, Yemen, India).

Interesting times ahead for Y934 as more people get tested.

I don't know why that new clade was named after Z6405. YFull itself gives Z6405 only 3 stars, and the SNP occurs also in haplogroup Q (https://yfull.com/tree/Q-Z5902/). M6512 is at the R-Z6405 level, but that SNP, too, only merits 3 stars, and recurs in two other places on the haplotree.

YP5677, also on the R-Z6405 level, gets 5 stars, and has not been found anywhere else on the tree. I have asked Yseq to offer an individual SNP test for YP5677 (or if necessary YP5679, another 5-star SNP with no recurrences).

Once the SNP test is ready, those who up until now have been classified R-Y934* may want to order it.
