More Sardinian samples which share SNPs with project members: Updated I-L160 tree

Click here to download our latest I-L160 tree

This tree shows a new I-Z27030* branch. This is one of many branches in I-M26 which contains both men in Sardinia and men from northern Europe. This branch contains samples 315-318 from P. Francalacci's Sardinian phylogeny (I-L160), and it also contains a cluster of our project members who share some distinctive STR marker values, for example DYS442=11 and DYS438=11. The Big Y for our project member shares 5 SNPs with the 4 Sardinian samples. We will update the tree soon to show these 5 SNPs (one of them is called Z27025).

One of our project members who belongs to this cluster has a Sardinian surname, so we expected that this cluster was represented in Francalacci's study. The other members are American and list northern European ancestry (England, Ireland and Alsace-Lorraine). Based on the number of unique variants found in the new Big Y results, probably the common ancestor of the northern Europeans with the Sardinian men lived more than 4,000 years ago. We will post a new tree showing the shared SNPs soon.

This update also shows two additional Big Y results, and some new SNPs names (shown in red).
