Group Trees

The phylogenetic trees for each Group were produced using Dave Vance’s SAPP web site. Over the past several decades many different software approaches were explored trying to find one which created diagrams useful to participants especially in the visual output. These packages included Fluxus, Phylip, Network, MEGA7, TreeView and others. The SAPP software creates a nice output containing the information participants will find helpful in understanding the relationships of those in each Group. SAPP is also very flexible in terms of the information one can input to the program.

Per the SAPP web page: Boxes are connected by lines of varying thickness, indicating how confident SAPP is in those connections. There are three "levels" of confidence - thick blue lines based on unambiguous STR, SNP, or Genealogy data; thinner blue lines based on less certain data (often on STR data alone), or thin grey lines where SAPP made what it thought was the best decision among several close choices without clear SNP or Genealogy support.

Within boxes there are three labels - the kit or node number in the middle, TMRCA calculations in green, and SNP and Genealogy labels in blue.

Trees cannot be created for Groups with less than 3 members.
