DNA Standards - Part 3

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 3."

Prior bullets are discussed in other parts of this series:
In "DNA Standards - Part 3" I further discuss the third and fourth 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:

  • analyze the DNA results accurately and in-depth (Standard 52) (Y-DNA STRs or SNPs; atDNA and X-DNA shared total DNA—shared, triangulated, or mapped segments, or genetic networks; mtDNA regions or locations; Y-DNA or mtDNA haplogroups; atDNA ethnicity estimates)
    • requires more in-depth understanding of the tools offered by testing companies and third-parties and how to accurately use those tools
    • may require correspondence with people to ask them about test taker links to ancestors or for permission to use third-party tools
  • integrate the thoroughly researched and analyzed DNA and documentary evidence; logically sequence and clearly illustrate the DNA analysis and the documentary analysis in a written conclusion; accurately and completely cite all sources (Standards 1–8, 55, 56, 65, 74)
    • write up the documentary evidence
    • explain why DNA is needed and give only as much DNA background as needed for this project (for example, if this case uses only Y-DNA evidence there is probably no need to explain what mtDNA and atDNA are)
    • explain the DNA evidence, correlating the shared DNA and/or mutations using tables and lineage charts


Additional bullets will be discussed in other parts of this series:
