Applying the DNA Plan- Worked Example

This is a continuation of my post Having a DNA Plan in Place with a worked example.

The 1st step is to formulate a research question or goal. My goal is to identify who is the mother of my great-grandmother. You can view my posts about this challenge here.

Next is to choose a DNA test. Since I am trying to identify a mother, I need to use mtDNA testing at FamilyTreeDNA.

The 3rd step is to find a candidate. In the chart below, I created to illustrate the possible candidates to take a test.

Brother 1, 3, and 4 are now deceased. Brother #2 is the best candidate. Remember, mothers pass mtDNA to all their children. There are no links that break this maternal line.

If Brother #2 wouldn't be willing to submit a sample, I would need to trace down a descendant of the probable mothers' sibling(s), then hope that the person(s) would take a test.

Hopefully, this post will help illustrate what a testing plan could look like with these 3 steps.

Do have any questions? Leave them in the comments.

Thanks for reading,

We all have seen the DNA testing commercials and the excitement they can bring to many people, but that isn't always the case. Over the years, the popularity of DNA tests has exploded. People have become interested in learning about their ancestry and where they came from. There is another thing about DNA tests-they can reveal family secrets. You probably have seen articles, videos, and even books about the effect on people's lives of DNA testing. This may change the way someone thinks about themselves and or their identity. In the theoretical example, "Sally" took a DNA test as well as her immediate family. 6 weeks later, she checked her results, all her family matched her, but Sally's sister didn't share enough DNA to be considered as a full sibling. Sally's mother tells her that sh...
