A critical mass of 75 Big Y results: 2019-11-03 tree for I-PH908

Click here to download our 2019-11-03 draft tree for I-PH908

There are now 75 completed Big Y results for I-PH908, almost all of these men are members of the I-P37 project at FTDNA. And there are at least three additional I-PH908 samples on the YFull tree, two are from Dante Labs and one is from a scientific study.

With so many samples to compare, each new Big Y result has a good chance of sharing downstream variants with a previous result, and we are finding many new branches as shown on this updated tree:

  • a branch which contains some men from Kazakhstan, they share 8 variants which haven't been named. They also share the distinctive marker value DYS389=14-33
  • a new I-BY198275 haplogroup which contains two known men. One of these men is more specifically P41.2/M359.2+.  The P41.2/M359.2 SNP was discovered many years ago and scientific studies have found this SNP in a small percentage of I-P37 men.
This tree also shows several updates in the I-FT16449 branch:

  • a new branch named I-Y126296 
  • a new branch named I-BY173308
  • a new branch named I-FT33812
  • a new sample that is I-BY169079*
Finally this tree shows two samples that are I-FT14506*. They are shown in the middle of the I-FT14506 section for reasons of space. They don't share any further variants below FT14506.
