DNA Special Interest Group - 9 Apr 2022

Today's Topic: Phasing, Imputing and Short Segments 

We will review the white papers put out by the various companies that detail how they go beyond simple "half matching" to better weed out false matches and to make comparisons between different chipsets. The review will include Ancestry's Timber phasing algorithm and Family Tree DNA's process for teasing out endogamy. We'll also explore recent examinations of the accuracy around short segments.

Today's Facilitator Michelle Wilson

About the DNA SIG

This group focuses on learning the methods for analyzing DNA test results. We study topics such as autosomal DNA, mitochondrial DNA, Y-DNA and surname projects, X-DNA and ancestral admixture results. We'll also investigate third-party tools for analyzing your raw data and comparing DNA and gedcom data with test kit results from companies besides the one you tested with.

DNA can break down genealogical brick walls once thought impenetrable – but only if you know how.

This SIG endeavors to be interactive and welcomes your questions. Get ready to put your DNA results to work for you!
