I-Y33765 draft tree December 23rd 2020

This is our latest draft phylogenetic tree for I-Y33765.  

The chart includes information from a FTDNA Big Y-700 test that has recently been completed on the Swedish arm of I-Y33765. This is the seventh Big Y test to have been completed within the I-Y33765 clade.This analysis for Mr Hallberg has identified five novel variants on his branch downstream from FT250135 (8564554, 8595182, 8603627, 15419322 and 17156586).  It seems possible that Dahlberg IN81271 may be derived for one or more of these novel SNPs.  Two earlier Big Y-700 tests on the Swedish arm, Eklund IN78306 and Jacobsson IN70815, have five and four novel variants respectively.

On the English arm, the FTDNA Big Y-700 test for Clement IN82043, which was completed in October, showed four novel variants.  One of these was at the position of a SNP that had been named Z22427 in 2015.  FTDNA initially identified the Clement polymorphism as Z22427 and this is how it was shown on the previous I-Y33765 draft tree dated November 7th, 2020 . However, while the Z22427 mutation is G > T, the Clement variant is G > A, and as a consequence, FTDNA have subsequently named this variant, FT374048.  Following my suggestion Yseq have designed primers for FT374048 and for another of the IN82043 novel variants, which has also been named, this time by YFull, as Y223449.  Clements YS32054 is currently being tested for both these SNPs at YSeq.
