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."

¹

Prior bullets are discussed in other parts of this series:

• 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) (For "DNA Standards - Part 2" see https://debsdelvings.blogspot.com/2019/03/dna-standards-part-2.html.)
  
• select matches and/or target-test others with the right test (Standard 51) (For "DNA Standards - Part 2" see https://debsdelvings.blogspot.com/2019/03/dna-standards-part-2.html.)
  

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:

• ensure enough people have tested to support the conclusion (Standard 53) (For "DNA Standards - Part 4" see https://debsdelvings.blogspot.com/2019/03/dna-standards-part-4.html.)
  
• support every parent-child link in the line from all test takers to the hypothesized ancestors with documentary evidence (Standard 2) (For "DNA Standards - Part 5" see https://debsdelvings.blogspot.com/2019/03/dna-standards-part-5.html.)
  
• identify familial relationships (where appropriate), present the conclusion as a genetic link only if the DNA supports that conclusion, explain any insufficient research (Standards 50, 56, 65, 74) (For "DNA Standards - Part 6" see https://debsdelvings.blogspot.com/2019/03/dna-standards-part-6.html.)
• make the DNA data available for verification, as much as possible within the limits of test taker permissions (Standard 54) (For "DNA Standards - Part 7" see https://debsdelvings.blogspot.com/2019/03/dna-standards-part-7.html.)
• publish or share only as a living test taker’s permission allows (Standard 57) (For "DNA Standards - Part 8" see https://debsdelvings.blogspot.com/2019/03/dna-standards-part-8.html.)
