DNA

If you want to use handouts or images I made please:
  • Notify Stephanie Saylor (DNAspecialist@FoundingFamilyLines.com) in advance that you are want to use it, and for what purpose. I made the presentations and diagrams to help people learn about genetic genealogy and would like to know what is helpful! I can also send you higher resolution graphics, if specifics are requested.

Autosomal DNA

Aids

  • Automatically Autosomal Worksheet: Includes worksheet, answer guide, and references for the presentation Automatically Autosomal
  • Cruising the Chromosomes Handout includes 3 activities and directions on reading chromosome browsers
  • atDNA Inheritance Presentation: Walks through how to calculate the amount of DNA that would be shared between 2 relatives or inherited from a relative
  • Ethnicity Evaluation Directions: How to create an ethnicity profile for yourself and your match (using data from 23andMe and AncestryDNA), track the information and navigate 23andMe’s Ethnicity Browser
  • Paternal and Maternal Labels on 23andMe: How to Label your 23andMe matches in DNA Relatives and sort your matches by if they are on your mother or father’s side of the family
  • Directions on uploading data to myHerritage (Coming soon)
  • Tracking your atDNA information (Coming soon)

Resources

  • Resources  that can help you learn more about atDNA. This includes: tools, databases, and scientific papers
  • “Cryptic Distant Relatives Are Common in Both Isolated and Cosmopolitan Genetic Samples” is a great paper (not by me) with 2 things any genetic genealogist should know and understand. You can find this paper on 23andMe’s list of publications “For the Scientific Community.”
    • Figure 3A: Is a skewed graph but illustrates the grouping of different relationships based on the number of segments and the amount of DNA (in cM) shared. It is good to notice that the more distant the relationship the more overlap you see between different levels of cousinship.
    • Table 2: The third column to the right depicts the % chance of matching your real cousin’s DNA. After 2nd cousins the chances of sharing DNA with your real cousin drops below 90%. After 3rd cousins it drops below 50%. The last 2 columns shows why distant cousin matches are more likely then close matches. It depicts the expected number of matches at different levels of cousinship. There are a lot more 7th great grandparents to descend from and thus more descendants of those ancestors to possibly match than 1st great grandparents.

Template

  • Research Log and Match Data Spreadsheet for Excel: I make my spreadsheets based on the question that I am trying to solve in my genealogy but this is a template that can be edited to suit your needs based on the processes that you want to use in solving your mysteries

Y-DNA

Aids

  • Y-DNA: What You Need to Know Handout outlines basics of Y-DNA
  • What, When, and Why the Y Worksheet Includes worksheet, answer guide, and references for the presentation “What, When, and Why, the Y”
  • Brothers yDNA MRCA: Outlines finding the possible number of generations to MRCA for your Y-STR match
  • Brothers yDNA Mapping: Provides practice in mapping out the possible Y-STR profiles of your ancestors to find a batter reference to use in your Y-STR research

Mitochondrial DNA

Aids

  • Handout: is a worksheet with questions, detailed answers, references, and resources that are useful in understanding when mtDNA can help move forward your research.

xDNA

Aids

  • Buried at X Handout: is a worksheet with questions, detailed answers, references, and resources that are useful when working with xDNA

Biology

Aids

  • From Spit to Screen Handout goes in depth on how the biology and genetics behind genetic genealogy can help you understand your results.
  • Beginning with basic biology Handout: Includes questions based on the biology behind genetic genealogy, their answers and the references for the entire presentation
  • Presentation Questions from Audience: Some Questions that were asked during and after the presentation through the presentation survey
  • Inheritance Activity Directions: Gives the directions to do the inheritance activity that shows how random chance provides variation in our DNA results even without taking recombination into account
  • Inheritance Activity: A game that can be played with a random number generator or a coin to illustrate how random chance provides variation in our DNA results even without taking recombination into account

Presentation:

Visual Phasing

Presentation to be given at  RootsTech2019

Visual phasing is a technique that uses DNA tests from three siblings to map out the DNA they received from their four grandparents. If you have been DNA- testing your family members, or would like to put those tests to good use, and are interested in solving a puzzle—like so many of us are, visual phasing may be right up your alley. Bring your own DNA tests, or we can use a generic example to walk you through the setup and have some visual phasing fun!

Handout, Template(PowerPoint) & Worksheet: PDF, PowerPoint
