You’ve Got Questions, We’ve Got Answers: Understanding DNA Testing

Let’s face it. DNA testing can be confusing.

Which family members do I test, and why? Once testing is complete, what do all the numbers mean, and where do I go from there?

Map Your Chromosomes – Even Without Living Grandparents

Map Your Chromosomes – Even Without Living Grandparents

Legacy Tree is excited to provide the Grandparent Inheritance Chart to the genealogical community. The basis for our tool is founded in the fact that at any given point in an individual’s DNA they can only have inherited DNA from a single paternal grandparent and from a single maternal grandparent. Therefore any DNA that you do not share with a tested grandparent has to have come from the other grandparent on that same side. The tool uses this information to create a chromosome map. But, what … ” Click here to read more…

Dealing with Endogamy, Part I: Exploring Amounts of Shared DNA

Autosomal DNA testing is a valuable resource for genealogists seeking to overcome recent brick walls in their family history, particularly in instances where traditional historical research is limited or unavailing. At Legacy Tree Genealogists, we frequently use autosomal DNA test results to answer questions regarding adoption, unknown paternity, or difficult to trace ancestors. To learn more about autosomal DNA testing see our previous blog post on the basics.Endogamy is the custom of …” Click here to read more…

 

Dealing with Endogamy, Part II: Test Multiple Relatives

In a recent blog post, Dealing with Endogamy: Part I, we explored the unique challenges of interpreting autosomal DNA test results for individuals from endogamous populations. Endogamy is the custom of marrying only within the limits of a local community, clan, or tribe over the course of many generations. Pedigree collapse, a related concept, occurs when two related individuals produce offspring. As a result, the number of unique individuals occupying locations in a pedigree …” Click here to read more…

 

How the X-Chromosome Solved a 100-Year-Old Adoption Mystery

(In order to protect privacy, names have been changed.)Lauren is the daughter of a woman named …” Click here to read more…

Sometimes there are rumors of descent from Native American, African, or Jewish ancestry. Other times there are no clues at all regarding an ancestor’s origins. In cases of ethnic origins, DNA testing is a unique tool that can assist in proving or disproving family stories, or revealing the origins of a “brick-wall” ancestor.There are three types of DNA tests: Y-chromosome, … ” Click here to read more…

 

Exploring Ethnicity with DNA, Part II: Autosomal Testing

In our Exploring Ethnicity with DNA, Part I blog post a few weeks ago, we reported on how to explore ethnic origins with Y-DNA and mitochondrial DNA. Whereas Y-DNA and mitochondrial DNA are limited to direct lines, autosomal DNA is inherited from many ancestors across several lines. On the other hand, while Y-DNA and mitochondrial DNA represent very deep ancestral lines, autosomal DNA sometimes does not reflect the contributions of more distant ancestors and is most useful for solving mysteries …” Click here to read more…
