I-PF4190 is the largest branch of I-M26 on the island of Sardinia, approximately 75% of the I-M26 men in Sardinia belong to I-PF4190. Paolo Francalacci sequenced the Y chromosomes of 1200 Sardinia men, 464 of them belonged to I-M26 and 345 of these belonged to I-PF4190.
Francalacci was able to create a tree based on these sequences, his I-PF4190 tree had approximately 147 branches and hundreds or low thousands of SNPs.
This I-CTS11338 tree is based on commercial NGS Y chromosome sequences (the Big Y etc). Our shows only 5 branches in I-PF4190 and approximately 50 SNPs. I-PF4190 has a MRCA who lived approximately 4100 years ago. I think this shows how much is remaining to be discovered about the Y-DNA tree.
This tree shows a new sample for a German ancestry men. When we see non-Sardinian men in I-PF4190, they often have German ancestry. He's not closely related to previous I-PF4190 German samples
For reasons of space we have moved the I-Z113 branch to a tree of its own, click here to find our first I-Z113 tree.
