DNA Quick Reference Notes

This post has been superceded by the updated documents and additional information in the Publications area of my website.

I've been promising students in the genetic genealogy sessions at the
Genealogical Research Institute of Pittsburgh (GRIP), the
Forensic Genealogy Institute, the Institute for Genetic Genealogy (I4GG), the Salt Lake Institute of Genealogy (SLIG), and many of my other presentations that I would put copies of my Quick Reference DNA documents on this blog where they could get copies. I'm finally fulfilling that promise so everyone can print color copies of the complete document even if only portions or non-color copies were provided in syllabus material.

Many of these have a Creative Commons license so others can improve them as long as copies are freely provided to others under the same licensing scheme.

Documents I keep close when doing genetic genealogy include:

QuickRef___DNA_mt_.pdf - mtDNA QuickRef with my mtDNA molecule diagram, mtDNA Regions and Common Ancestor Matches chart, Family Tree DNA Match List Threshold chart, Native American mtDNA Haplogroups table, and Heteroplasmy notes.

QuickRef___DNA_Y.pdf - Y-DNA STR Marker chart noting fast-mutating markers, conversion between AncestryDNA and Family Tree DNA marker values, and noting which Family Tree DNA markers were tested by AncestryDNA.

QuickRef_DNA_inherited_atDNA.pdf - table with Percentage of Shared Autosomal DNA averages by relationship, some shared percentage ranges and some cM values also included.

Xinherit_chart_femalecolored.pdf - X-DNA Inheritance Chart for Female Focus Person.

Xinherit_chart_malecolored.pdf - X-DNA Inheritance Chart for Male Focus Person.

  3. Just being able to see the concepts in a chart chart is an immense help!

    1. I'm glad these charts are useful to so many people. For me, seeing an illustration or chart helps understanding complex concepts.
