Blaine Bettinger's Shared cM Project – An Update

One of the greatest advantages of the DNA Testing Community is the participant's willingness to share. This article and chart are an example. I am pretty sure I sent in my donations to this project. In any case, I am surely glad all these other people did, enabling the author to compile actual data for comparisons.

The Shared cM Project – An Update

Posted on 25 May 2015 by Blaine Bettinger

C = cousin R = removed

As you might recall, a few months ago I sent out a call (“Collecting Sharing Information for Known Relationships“) for information about the amount of DNA shared by people having a known genealogical relationship. I was hoping to get a better picture of the ranges of the amount of DNA shared by people in these relationships (through about the third cousin range). The incredibly generous genetic genealogy community responded by submitting data bout more than 6,000 relationships!

I posted information a few weeks ago (“Collecting Sharing Information for Known Relationships – Part II“), but today I have an update.
