DNA Standards - Part 2

For "DNA Standards - Part 1" see https://debsdelvings.blogspot.com/2019/03/dna-standards-part-1.html. In the first part I paraphrased the standards for using DNA evidence for genealogy into bullet points.

This is the post for "DNA Standards - Part 2."


In "DNA Standards - Part 2" I further discuss the first two bullets. The main bullets indicate considerations when using DNA to help answer a research question; sub-items explain what is needed to accomplish the tasks defined in the main bullet:

  • test the right descendants with the right test(s) at the right company or companies to obtain the information needed to answer the research question (Standard 51)
    • requires identification of living person(s) likely to have the DNA needed to answer the research question
    • requires an understanding of the inheritance path for each type of DNA (Y-DNA, mtDNA, atDNA, X-DNA)
    • requires an understanding of the different tests offered by each company
  • select matches and/or target-test others with the right test (Standard 51)
    • requires understanding the tools offered by testing companies and third-parties and how to accurately use those tools
    • may require correspondence with people to ask them to take a test (which requires understanding the cultural norms that might affect responses)
Additional bullets will be discussed in other parts of this series:
