Finally, a Big Y sample in a branch with the 1000 Genomes Puerto Rico samples: 2020-02-12 tree for I-Z113

This draft tree shows several updates:

A new Big Y-700 result for a man with El Salvador ancestry is CTS3203+ Z97+ Z107+ Z110+ etc. Previously these SNPs had only been found in two anonymous samples from Puerto Rico, these two men were part of the 1000 Genomes project.

The Puerto Rican men share at least 9 additional SNPs with each other, the El Salvador man has negative results for some of these SNPs, and no result was reported for other SNPs. There is another man in the I-P37 project with Puerto Rico ancestry, his Genographic 2.0 test reported CTS2303+ Z97+ Z107+ results.

(Update 2020-02-21: This draft tree shows a branch called I-CTS2181 but this name is incorrect. The correct name is I-Y2181. We have already corrected the name on our 2020-02-20 tree which is available on this blog. So far the only known members of this branch are the two 1000 Genomes samples, Y2181 wasn't tested in the Genographic 2.0 test).

FTDNA's Big Y Block Tree and Haplotree show I-Z110 as a parallel branch to I-CTS3203. This is incorrect, Z110 and CTS3203 are currently equivalent SNPs as shown on our I-Z113 tree linked above and on YFull's I-Z113 tree (click here)

FTDNA's Big Y Block Tree and Haplotree show Z113, Z27246 and FT59019 as equivalent SNPs. This is incorrect, the El Salvador man is Z113+ Z27246+ but FT59019-. Almost all other Z113+ Z27246+ mean are FT59019+. 

We now know that I-Z113 has three immediate child branches: the large I-FT59019 branch, the small I-CTS3203 branch, and an I-Z113* branch which currently contains a single sample with Spanish paternal ancestry.
