DNA Research Framework 1 - Understanding DNA Basics

This post relates to Part 1 of the DNA Research Framework - Understanding DNA Basics.  

There are five parts to the DNA Research Framework.  

  1. Understand DNA Basics
  2. Know what you are working with
  3. Combine genetic and genealogical research
  4. Use genetic research to prove and expand your pedigree
  5. Continuous review

Within the framework we apply a DNA research methodology to ensure we systematically and methodically review our results, to improve our productivity and success rates.

The following blog posts provide more detailed information about the DNA Research framework, applying the DNA Research Methodology and building your DNA analysis skills:
This post contains reference material to supplement the webinar series recently held at the Society of Australian Genealogists: Part 1 - Understand DNA Basics.  Whether you are planning to look at your results using a broad analysis approach, or undertaking chromosome analysis, these links should help you develop the key concepts required to be able start your DNA analysis journey.  The ISOGG site also has a lot of useful material refer - ISOGG Beginners' guides to genetic genealogy.


Understanding DNA Basics - Broad approach
When you first start reviewing your DNA results it is best to approach them broadly and understand basic concepts before moving to analysing results at the chromosome level.  These blog posts will aid your learning so work through them systematically.  

Understanding DNA Basics - Chromosome analysis
After working with your DNA results broadly for a time you will want to delve into analysing your results at the chromosome level.  To confirm your pedigree beyond 3rd cousins or where there is no documented paper trail  (with the exception of parent/child and sibling relationships) you need to undertake detailed chromosome analysis, using segment data.

Firstly, read and understand the information in the broad approach section (above), before through working through the following posts.   These are more relevant for working with your DNA results at the chromosome level.


Suggested activities

Click this link to find some activities to help you apply 'Module 1' in practice.  These can be done using the GEDmatch 'free' version, using the new site.  The Tier 1 subscription has more tools but it is recommended that you start with the free version and master that first.
