Part Two: MyHeritage DNA Theories of Family Relativity
Theories of Family Relativity is part two of a series of articles to help you navigate MyHeritage DNA matches and tools. Read part one here. Genetic genealogy is founded on the observation that when two testers share DNA, they share common ancestry. In the case of autosomal DNA tests (like the one offered by MyHeritage), the ancestor who was the source of that shared DNA could be through any of the respective testers’ ancestral lines and could be any number of generations back in the … [Read more...]
Autosomal DNA Test Results: Using Ethnicity Estimates to Generate Genealogical Hypotheses

6 Signs of Misattributed Parentage in Your Genetic Family Tree
While DNA testing and genetic evidence are certainly useful for breaking down challenging historic brick walls, the implications of DNA testing can also hit closer to home in the modern era when it comes to research on misattributed parentage. In cases of adoption, unknown parentage or misattributed parentage, genetic genealogy methodologies enable identification of close biological ancestors whose identities might otherwise remain unknown, and which represent immediate brick walls for any … [Read more...]

Five Ways to Use the New DNA Coverage Estimator Tool at DNA Painter
The DNA Coverage Estimator is now available and makes the process of identifying matching ancestors through DNA much simpler than ever before. In April 2018, Legacy Tree Genealogists published an article by Paul Woodbury introducing the concept of DNA coverage – the amount of an ancestor’s DNA represented in a DNA database through the test results of their tested descendants. Different descendants of an ancestor inherit different portions of that individual’s DNA. Therefore, they have … [Read more...]
