Roots of Haplogroup R1b: STR111 tree

Today, I want to present the STR111 tree of haplogroup R1b, and I used the same method as before.
Due to the large number of individuals having haplogroup R1b I decided to focus only on the roots of this haplogroup. This is the biggest tree I created so far with a total of 1141 individuals.

Most of these individuals are from the UK and Ireland.

Next, I decided to exclude all samples with US or unknown ancestry, I ended up with 738 individuals, still a huge tree. Because of the size I still cannot use FITCH for a "fine-scale" tree but "only" NJ tree at SplitsTree.

Finally,  I decided to exclude all samples with US, UK, Irish or unknown ancestry, the vast majority of samples. I ended up with 103 individuals. Here, FITCH was used and showed a much better tree.
