DNA  -  101
by  Robert B. Noles

Genetic  Genealogy
What do I need to Know ?

 

DNA - 101

 

For most of us, who have limited backgrounds in the biological sciences, the subject of DNA testing for genealogical research may be difficult to comprehend without a little preparation.  This DNA-101 Section for the Regional and Surname DNA Projects for Wiregrass Georgia is an important prerequisite to the proper understanding and the use of the test results obtained so far and for the test results to be obtained in the future.

 

While the articles included in DNA-101 are intended to be informative, this is by design a brief and incomplete explanation of a very complex subject.  You may want to consult scientific literature concerning this subject for more rigorous details and alternative views.  Hopefully, there is sufficient information included here in DNA-101 and in the other Sections of the Genetics Sections on the Huxford Web site to satisfy your need to know and understand how we are using genetics to support genealogical research.

 

DNA-101 by the Blair Genealogy Project is an excellent resource to explain the extremely complex and confusing science of Genetics and DNA in layman terms.  The Blair Project articles and the Huxford articles with links below, address DNA and DNA testing only as it applies to Y-chromosome and mitochondrial DNA testing and genealogy.

 

The International Society of Genetic Genealogy (ISOGG) is a non-commercial non-profit organization dedicated to helping with a better understanding of the use of new tools for genealogy research via genetic testing.  There are NO dues or fees to join, it is entirely self-supporting by its members.  YOU choose what you wish to give.  Whether it's your time to give a presentation or host a workshop at your local genealogical society, or create photocopies to promote the society at a convention, it's up to you. You will not be asked to spend your time or contribute in a way you do not wish to.  You may never end up participating in that manner, but may just join to learn and network, and that's okay too.  The ISOGG Site Map provides a quick way for you to find a variety of DNA - 101 helpful articles.

 

 


 

REMEMBER:  Your descendants, 50 to 100 years from now, will find your birth certificate, your marriage license, your death certificate, your Census records, your drivers license, your deeds, etc.; however, they will be very disappointed if they do not find your genetic genealogy test results.  Everyone interested in accurate and proven genealogies and family histories should be tested.

 

 

No blood or needles are required for you to be obtain a genetic genealogy test.
