This page is under construction, and will never be finished. It was created for my own reference and has been made available on the off chance it could be useful to someone else.

A collection of various files including phylogenetic trees, and Excel spreadsheets can be found here.

ySearch Modals:

Mike Walsh - Modal from R-L21 Project research group, 96 markers

STR Clusters

Some of these clusters have associated SNPs, while the majority of them are only loosely defined in terms of STRs. This is by no means an exhaustive list, and there are very many smaller clusters not included.

11-13 Combo Cluster

9919 Cluster

ySearch Modals:

Bill McCeney - Mode: R-L21*with 9-9 & 19-19 Hts

Northwest Irish (R-M222)

By far the biggest cluster of R-L21 found to date in terms of sampling, but not likely the oldest.
Also known as Irish Type I.
