April 26 at 1 PM – Dealing with Endogamy and Pedigree Collapse in DNA research

This event has already happened.

Our next Zoom meeting will be April 26 at 1 PM.

A surprising number of us have a problem with Endogamy in our DNA research (where a relatively small group of people regularly have intermarried). Typically associated with the Ashkenazi Jewish, it is also typical of the French Canadians, people who lived in Appalachia for generations, native Americans, Mennonites, and the Amish.

But more of us have a problem which is called Pedigree Collapse. In this case, members of the same family intermarry in recent generations and so DNA relationships are closer than they might appear. How many of you have a situation where brothers married sisters? In this case, what appear to be 2nd cousin relationships are instead quite similar in DNA to first cousin relationships. This is called Pedigree Collapse.

This meeting will discuss these problems and how to analyze your DNA relationships to better understand how to deal with Endogamy or Pedigree Collapse.
