About the C-P39 Y DNA Project Updates Website
C-P39 Y DNA Project Administrators: Marie Rundquist and Roberta Estes  Project Advisor: Dr. David Pike


The C-P39 Y DNA Project Updates website is a dynamic, data visualization platform for C-P39 Y DNA Project. Graphical techniques and methods have been applied so that project members and website visitors may gain a rapid understanding of how results compare without having to read through pages of row and column information, trying to make sense of the numbers. C-P39 Haplogroup DistributionGenetic distance, Most Recent Common Ancestor (MRCA), and Big Y relationships  formerly buried in the data rise to the surface, with greater clarity, when presented in easily interpreted graphical formats.

The C-P39 Y DNA Project Updates website is updated frequently as new information becomes available. Reference the C-P39 Y DNA Project Family Tree DNA website for complete information about the project.

C-P39 Y DNA Haplogroups

Y-Chromosome DNA Haplogroups are based on SNPs, Single Nucleotide Polymorphisms, that occur in the non recombining region of the Y-chromosome. Haplogroup C-P39 is defined by the SNP P39. This mutation is believed to have occurred at least 15,000 years ago. C-P39 is found in the Americas.

SNPs that are characteristic of this project include, thus far, the C- P39+ (our project baseline) and new subclades based on novel variants and SNPs submitted by the C-P39 Big Y project.

Big Y C-P39 Y DNA test participants will find new, distinguishing SNPs showing as labels in their individual project results.  In labeling and grouping the data on the site, outside of referencing the new SNPs for further categorization of results, the project has maintained the same information as already published on our site without change. For all C-P39 Big Y results in our project, there was no change to the initial C-P39 positive (+) finding during analysis of the novel variant and SNP information submitted; so, this SNP should stand as the initial SNP tested by project members who join. 

Updates to the C-P39 Y Tree

Updates to the Y Tree based on the C-P39 Y DNA Project's Big Y novel variant and SNP submission as related to regions represented in the C-P39 Y DNA Project as of December 2017 are summarized below:
  • North American Appalachian Region - Multiple Surnames: C-P39+ C-Z38940+ [Updated 7/24/2017]
  • North American Canada - Multiple Surnames: C-P39+ C-Z30765+
  • North American Canada - Multiple Surnames: C-P39+ C-Z30750+ 
  • North American Canada: Acadia (Nova Scotia:  C-P39+ C-Z30750+ 
  • North American Canada: Acadia (Nova Scotia): C-P39+ C-Z30754+
  • North American Southwest Region: CP39+ C-Z30747+

The following SNP (BY18405+) was found for one Big Y member in the entire Big Y system, as reported here: 

  • North American Canada: Newfoundland: C-P39+ C-BY18405+ [Updated 9/6/2017]
  • North American Canada: New Brunswick: C-P39+ C-BY22870+[Updated 9/6/2017]
  • North American Canada: Gaspe, QC: C-P39+ C-BY22870+[Updated 9/6/2017]
The ancestors of two families represented in the study, one in the Pacific Northwest, another in the North American Southwest did not experience any mutations in the New World and Big Y results are within the current genetic boundaries of the C-P39 SNP haplogroup as noted. [Updated 6/23/2017]

C-P39 Y DNA Subclades

New C-P39 Y DNA haplogroup subclades (branches) resulted from the project's Big Y test results as shown in the diagram below.  At the far left of the diagram is the root C-P39 SNP; each of the subclades that follow represent subordinate branches, or subclades of the C-P39 haplogroup.
