Genetic Genealogy
We discussed genealogy DNA tests in Chapter 8. Here we focus on some practical matters to aid your engagement with genetic genealogy. We’ll survey which company you might choose for conducting your DNA test(s), explain how to interpret your results, and answer some common questions posed by genetic genealogy beginners (and even by some more advanced practitioners, too). Before seeking a company, identify what you hope to achieve. Different companies offer different types of tests, which reveal different genetic features and answer different questions, so knowing what you want to get from a DNA test will then allow you to choose from a list of companies offering that feature. Once you have a short list of suitable companies, you can choose based on practical criteria—price, convenience, appeal of website and presentation of data, privacy policy, and other factors. When you receive the results, you may want some help in interpreting the data and in identifying “matches,” your close and distant DNA relatives. We’ll also discuss a recommended free site, Gedmatch, and offer help for adoptees and others lacking known biological connections. In the latter half of the chapter we’ll explain some of the arcane terminology and address some common misconceptions encountered in the genetic genealogy community.
